Answer:
A) √7 + 4
B)2√15
D)√23+√8
Step-by-step explanation:
The options are:
A) √7 + 4
B)2√15
C)8-√5
D)√23+√8
E)√80-3
Analysing A.
√7+4 = 2.64575131106459 + 4
√7 + 4 = 6.64575131106459
Analysing B
2√15 = 2 * 3.87298334620741
2√15 = 7.74596669241483
Analysing C
8-√5 = 8 - 2.23606797749978
8 - √5 = 5.76393202250021
Analysing D
√23+√8 = 4.79583152331271 + 2.82842712474619
√23+√8 = 7.62425864805890
Analysing E
√80-3 = 8.94427190999915 - 3
√80-3 = 5.94427190999915
After the above analysis;
Options A, B and D answer the question
Answer: 7+4
5/15
/80-5
Step-by-step explanation:
Solve for b:
C = 15 + ab
Answer:
b = C - 15
a
Step-by-step explanation:
C = 15 + ab
C - 15 = ab
a a
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]C = 15 + ab[/tex]
Subtract sides 15
[tex]C - 15 = - 15 + 15 + ab[/tex]
[tex]C - 15 = ab[/tex]
Divided sides by a
[tex] \frac{C - 15}{a} = \frac{a \times b}{a} \\ [/tex]
[tex] \frac{C - 15}{a} = b \\ [/tex]
[tex]b = \frac{C - 15}{a} \\ [/tex]
Done....

Find the slope between the two points.
(3,7) (2,9)
m= 2
m= -2
m= 0
m = 1
Given the ordered pairs find the value of r that makes the slope equal to the given value (3 , r) and (7 , 2) m= 1/4
Possibles answers
A) r= -1
B) r= 2
C) r=1
D) r =3
E) r=0
Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula, then equate to [tex]\frac{1}{4}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, r) and (x₂, y₂ ) = (7, 2)
m = [tex]\frac{2-r}{7-3}[/tex] = [tex]\frac{2-r}{4}[/tex] , then
[tex]\frac{2-r}{4}[/tex] = [tex]\frac{1}{4}[/tex] ( since denominators are both 4, equate the numerators )
2 - r = 1 ( subtract 2 from both sides )
- r = - 1 ( multiply both sides by - 1 )
r = 1 → C

A wire that is 80 centimeters long is shown below. The wire is cut into two pieces, and each piece is bent and formed into the shape of a square. 80 cm wire Suppose that the side length (in centimeters) of one square is x cm. Express the perimeter of the big square in terms of x. (1 point)
Answer:
The perimeter of the second(big) square = [tex]\mathbf{4 \times \begin {pmatrix} \dfrac{80-x}{4} \end {pmatrix}}[/tex]
Step-by-step explanation:
From the information given:
The length of the piece of the wire = 80 cm
When being cut into two pieces;
the length of the first wire = x
Then the length of the second(big) wire will be = 80 - x
However, when each piece is bent to a square shape
The length of one side of the first square = [tex]\dfrac{x}{4}[/tex]
The length of one side of the second(big) square; [tex]\dfrac{80-x}{4}[/tex]
Area of a square = l² ( where l is the length of the sides)
For the first square
A₁ = [tex](\dfrac{x}{4})^2[/tex]
A₁ = [tex]\dfrac{x^2}{16}[/tex]
The area of the second(big) square is:
A₂ = [tex](\dfrac{80-x}{4})^2[/tex]
A₂ = [tex](\dfrac{(80-x)^2}{4})[/tex]
The perimeter of the first square = [tex]4 \times \dfrac{x}{4}[/tex]
The perimeter of the second(big) square = [tex]\mathbf{4 \times \begin {pmatrix} \dfrac{80-x}{4} \end {pmatrix}}[/tex]

How do you solve this?!!
Answer:
135°
Step-by-step explanation:
Step 1:
100° + 35° + 180° - ? = 180° Sum of a Δ/Vertical ∠'s
Step 2:
315° - ? = 180° Combine Like Terms
Step 3:
315° = 180° + ? Add ? on both sides
Step 4:
315° - 180° = ? Subtract
Answer:
? = 135°

Write the word sentence as an equation. Then solve.
A number x divided by −9 is −16.
Equation = ?
Solution x = ?
Answer:
x = 144
Step-by-step explanation:
When a number is being divided by another number , it will be that number/the number that is dividing that number.
Equation:
x/-9 = -16
x = -16(-9)
x = 144

2 ( 7 + 8 ) =
Answer:
30
Step-by-step explanation:
Original Equation: 2(7 + 8)
So you have to multiply 2 by 7 which equals 14
Then you multiply 2 by 8 which equals 16
Your equation should now look like this: 14 + 16
Add 14 and 16 together.
Your answer is 30
