Answer: [tex]-56\cdot 25\cdot 4 = -5600[/tex] .
Step-by-step explanation:
Associative property of multiplication : We can group numbers to multiply in any order like
[tex]p\times (q \times r) = (p\times q )\times r = p\times q\times r[/tex], where p , q and r can be any expression.
The given expression : [tex]-56\cdot 25\cdot 4[/tex]
By using associative property of multiplication, we have
[tex]-56\cdot(25\cdot 4)\\\\= -56\cdot 100\\\\=-5600[/tex]
Hence, [tex]-56\cdot 25\cdot 4 = -5600[/tex] .
PLZ HELP I will give the brain!! Which of the following statements is true about completing the square? 1. When completing the square, add the square of half the coefficient of x to only the x^2+bx side of the equation. 2. When completing the square, add the square of half the coefficient of x to both sides of the equation. 3. When completing the square, subtract the square of half the coefficient of x from both sides of the equation. 4. When completing the square, add half the coefficient of x to both sides of the equation.
Answer:
Option 2
Step-by-step explanation:
When completing the square, you have to find the number that will allow you to find the perfect square trinomials and when you factor that it should get the form a^2 + 2ab + b^2 and if a is equal to 1, then to find b, you have to take the half of the coefficient and square it because of the equation, and to maintain a balanced equation, you have to add it to both sides (same to both sides)
Hope this helped.

True or false: equilateral triangles can be classified as acute right or obtuse
Answer:
False
Step-by-step explanation:
Equilateral triangles can only be acute.
Because a triangle can only have 180 degrees in angles, in an equilateral triangle all angles must be less than 90 degrees since they all measure the same (60 degrees)
I hope this helps!
-TheBusinessMan
Answer: False.
Step-by-step explanation:
All the angles of an equilateral triangle are 60° all less than 90° so only acute is correct.
The weight of meteorite A is 2 times the weight of meteorite B. If the sum of their weights is 69 tons, find the weight of each.
Answer:
Meteorite A= 46 Meteorite B = 23
Step-by-step explanation:
We can solve this problem by making an equation in which we add the weights, A + B = 69
We are told that A is equal to 2 times the weight of meteorite B, in other words, A is equal to 2B
We can make this into an equation and solve for B'
A + B = 692B + B = 69 Substitute A for 2B3B = 69 Add like terms[tex]\frac{3}{3}[/tex] B = [tex]\frac{69}{3\\} \\[/tex] Divide each side by 3 to isolate the BB= 23In order to solve for A, we simply input B=23 into 2B
A = 2BA = 2(23)A = 46Check:
A + B = 69
46+23 = 69
69 = 69

Jamal recorded three values for measuring water in a graduated cylinder. The
values were 25.85, 24.1, and 24.56. What was the TOTAL amount of water
measured? *
Your answer
Answer:
74.51 mlStep-by-step explanation:
Hello!!!
from the problem statement we can infer that Jamal had a container of water where he fetches from to fill the graduated cylinder.
More so, after some couple of trails he recorded as follows
25.85, 24.1, and 24.56.
Hence the total amount of water he measured out of the container after three trials is
25.85+24.1+24.56= 74.51 ml
(assuming the cylinder is calibrated in ml)
The total volume of water he measures is 74.51 ml

Step-by-step explanatio
The number i¹³ is given by the equation A = i
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The complex number is n = i¹³
Now , the value of A is A = i¹³
On simplifying the equation , we get
i = √ ( -1 )
i² = -1
i³ = -i
i⁴ = 1
So ,
i¹³ = i¹² ( i )
The value of i¹² = ( i⁴ )³
The value of i¹² = ( 1 )³
The value of i¹² = 1
Now , the value of i¹³ = i¹² x i
On simplifying the equation , we get
The value of i¹³ = 1 x i
The value of i¹³ = i
Hence , the value of i¹³ = i

factorise the polynomial X square + X - 10...what is the answer please solve fast...I will mark u brainliest but no wrong answer please
Answer:
(x + [tex]\frac{1}{2}[/tex] + [tex]\frac{\sqrt{41} }{2}[/tex] )(x + [tex]\frac{1}{2}[/tex] - [tex]\frac{\sqrt{41} }{2}[/tex] )
Step-by-step explanation:
solve the polynomial for x then express in product of factor form
Solve
x² + x - 10 = 0 ( add 10 to both sides )
x² + x = 10
Using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2([tex]\frac{1}{2}[/tex] )x + [tex]\frac{1}{4}[/tex] = 10 + [tex]\frac{1}{4}[/tex]
(x + [tex]\frac{1}{2}[/tex] )² = [tex]\frac{41}{4}[/tex] ( take the square root of both sides )
x + [tex]\frac{1}{2}[/tex] = ± [tex]\sqrt{\frac{41}{4} }[/tex] = ± [tex]\frac{\sqrt{41} }{2}[/tex] ( subtract [tex]\frac{1}{2}[/tex] from both sides )
x = - [tex]\frac{1}{2}[/tex] ± [tex]\frac{\sqrt{41} }{2}[/tex]
Thus corresponding factors are
(x - (- [tex]\frac{1}{2}[/tex] - [tex]\frac{\sqrt{41} }{2}[/tex] ) ) and (x - (- [tex]\frac{1}{2}[/tex] + [tex]\frac{\sqrt{41} }{2}[/tex] ), that is
(x + [tex]\frac{1}{2}[/tex] + [tex]\frac{\sqrt{41} }{2}[/tex] ) and ( x + [tex]\frac{1}{2}[/tex] - [tex]\frac{\sqrt{41} }{2}[/tex] )
Thus
x² + x - 10 = ( x + [tex]\frac{1}{2}[/tex] + [tex]\frac{\sqrt{41} }{2}[/tex] )(x + [tex]\frac{1}{2}[/tex] - [tex]\frac{\sqrt{41} }{2}[/tex] ) ← in factored form

Please help me with my homework i will give you alot of points
Answer:
see below
Step-by-step explanation:
7. 1/3 ( n+2) = 5

Subtract 2 from each side
n+2-2 = 15-2

8.x = bills
He started with 300 and paid 1/4 of the bills and ended up with -50
300 - 1/4 x = -50
Rearranging the order on the left
-1/4x + 300 = -50
Answer:
(A) [tex]-\frac{1}{4}x+300=-50[/tex]
Step-by-step explanation:
I "reversed" this problem to find the equation that works for it.
The balance was originally $300. If he's now at a balance of -50$ after paying off [tex]\frac{1}{4}[/tex] of his bills, then [tex]\frac{1}{4}[/tex] of his bills are $350, since [tex]300 - (-50) = 350[/tex].
If [tex]\frac{1}{4}[/tex] of his bills are $350, then his full bill is [tex]350\cdot4=1400[/tex]$.
So I tested each equation, where [tex]x=1400[/tex] to see if the equation worked out.
For a:
[tex]-\frac{1}{4}x + 300 = -50\\\\-\frac{1}{4}\cdot1400 + 300 = -50\\\\-350 + 300 = -50[/tex]
-350 + 300 is indeed -50, so I knew this equation works.

Answer:
x=5/2
Step-by-step explanation:
(2/7)^2x *(2/7)=(2/7)^6
(2/7)^(2x+1)=(2/7)^6
Equate indices
2x+1=6
2x=6-1
2x=5
x=5/2
Answer:
When multiplying the same number, raised to different powers, you carry the number forward so (2/7)^6 is part of the answer.
Now, we have to calculate the exponent.
2x + 1 = 6
So, the answer is x = 2.5 which means
[2/7]^(2*2.5) x [2/7]^1 = [2/7]^6 which equals
[2/7]^5 x [2/7]^1 = [2/7]^6

Write the equation of the line that passes through the points (1,4) and (-7,1). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
There are two possible answers
y - 4 = (3/8)(x - 1)y - 1 = (3/8)(x + 7)There are two answers because there are 2 points given. Both equations convert to the slope intercept form equation y = (3/8)x + 29/8
=================================================
Work Shown:
First we need the slope
m = (y2 - y1)/(x2 - x1)
m = (1-4)/(-7-1)
m = -3/(-8)
m = 3/8
-------------------
Using this slope along with the point (x1,y1) = (1,4) gets us the following equation
y - y1 = m(x - x1)
y - 4 = (3/8)(x - 1)
which is one way to express the equation in point-slope form
-------------------
Or we could easily use the other point as (x1,y1). The order of the points does not matter.
y - y1 = m(x - x1)
y - 1 = (3/8)(x - (-7))
y - 1 = (3/8)(x + 7)
is another valid answer.
