Answer:
He is incorrect.
Step-by-step explanation:
The correct answer is 4,160.
Answer:
3. He is incorrect because he should have multiplied the exponents.
Step-by-step explanation:
6∧5 × 6∧4 = 369 Incorrect
Correct: 6∧5 = 7776
6∧4 = 1296
7776 × 1296 = 10,077,696
1. He is not correct, therefore the first answer is wrong.
2. You do not subtract the exponents unless one of the exponents is negative and you have the same bases. You have the same bases in this equation, however, neither one of them are negative. Therefore, the second answer is wrong.
3. The third answer is correct because if you were adding the two terms together then you would add the exponents together then multiply the base as many times as needed. However, since you are multiplying the two terms together, you also need to multiply the exponents together. From there, you then multiply the terms and get your answer.
4. The fourth answer is also incorrect because you need to multiply the bases together in order to get a correct answer.

Solve the following equation for d.
T= Gd - N3
Answer: [tex]d=\frac{T+N3}{G}[/tex]
Step-by-step explanation:
To solve for d, we want to use algebraic properties to isolate d.
[tex]T=Gd-N3[/tex] [add both sides by N3]
[tex]T+N3=Gd[/tex] [divide both sides by G]
[tex]\frac{T+N3}{G} =d[/tex]
[tex]d=\frac{T+N3}{G}[/tex]
Now, we know that [tex]d=\frac{T+N3}{G}[/tex].

Which of the following is a term in the
expression 3x2 + 5x +9?
Answer:
Two.
Step-by-step explanation:
In algebra, a term is either a single number or variable, or numbers and variables multiplied together. In any equation, all of the numbers there that aren't divided by a mathematical operation (times or divide symbols) are terms.
3x2 isn't a term, it's an expression - but 5x and 9 are, so therefore there are 2 terms.

Answer:
[tex]\large\boxed{1+i}[/tex]
Step-by-step explanation:
[tex]$\frac{4+2i }{3-i} $[/tex]
Factor the numerator
[tex]$\frac{2(2+i) }{3-i} $[/tex]
Multiply both numerator and denominator by the conjugate of the denominator.
[tex]$\frac{2(2+i) }{3-i} \cdot \frac{3+i }{3+i} = \frac{2(2+i)(3+i) }{9-i^2} $[/tex]
Once [tex]i^2=-1[/tex]
[tex]$\frac{2(2+i)(3+i) }{10} $[/tex]
Solving the numerator
[tex]2(2+i)(3+i) = 2(6+2i+3i+i^2) = 2(6+5i-1)=2(5+5i)[/tex]
[tex]$\frac{2(5+5i)}{2 \cdot 5} =\frac{5+5i}{5}=\boxed{1+i} $[/tex]
1. Minti can do a piece of work in 12 days. Minti and Rinki together can finish the work in 8 days.
Find: (a) the number of days in which Rinki alone can finish the work.
(b) the work left if Rinki alone works on it for 4 days.
Answer:
Minti - 12 days
Minti & Rinki - 8 days
Use Formula 3
time= (12 * 8) / (12 -8)
time = 96 / 4
time for Rinki alone = 24 Days

which expression is equivalent to the given expression square root of 45
Answer:
[tex]3 \sqrt{5} [/tex]
Step-by-step explanation:
Solve using Surd
[tex] \sqrt{45} = \sqrt{9 \times 5} \\ = \sqrt{ {3}^{2} \times 5 } \\ = 3\sqrt{5} [/tex]
The expression 3√5 will be equivalent to a square root of 45.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given the expression √(45)
⇒ √(9×5)
⇒ √(3²×5)
⇒ √(3²)√(5)
Since the square root of a square is the same number
So,
⇒ 3√5
Hence "The expression 3√5 will be equivalent to a square root of 45".

Find the value of x and YZ if Y is between X and Z.
3. XY = 2x + 1, YZ = 6x, and XZ = 81
Answer:
1) 2 1/4 inches (2.25)
2) 5.3 millimeters
3) X=10 and YZ=60
Step-by-step explanation:
Number 1, you just add the measurements because n and q is the start and end of the line segment.
Number 2, you are given the whole measurement, and you know FG which is 9.7, so you subtract the 15 (whole measurement) by 9.7, which is 5.3.
Number 3, you know that XY and YZ equal XZ, so 8x+1 would equal 81. Do the math, you would get 8x=80 and then x=8. Now you know x, plug it in for 6x, so 6(10)=60.

In triangle ABC, the measure of angle B is 50 degrees. Give possible values for the measures of angles A and C if ABC was an acute triangle.
Answer:
Step-by-step explanation:
An acute triangle is a triangle that has all the measures of its angles to be less than 90° i.e none of the angles is greater than 90°
Since of angles in a triangle is 180, hence <A + <B + <C = 180
Given
<B = 50
50 + <A + <C = 180°
<A + <C = 180-50
<A + <C = 130°
Note that all the angles of an acute triangle are also different
Hence the possible values of A and C are 60° and 70° (since their sum must give is 130°)
Another possible values are 55° and 75°
60° and 70°
55° and 75°

Explanation:
The tickmarks indicate which segments are the same length. On the left side, the single tickmark segments are the same length, and the same can be said about the double tickmarks segments as well. Because of this, the segment x cuts the diagonal sides in half.
The segment x is known as a midsegment of the triangle. It is half as long as the parallel side of 24 units. So x = (1/2)*24 = 12.
WILL GIVE BRAINLIEST! Determine the coordinates of the point on the straight line y=3x+1 that is equidistant from the origin and (−3, 4).
Answer:
Step-by-step explanation:
The distance between a point (x,y) and the point (-3,4) is
d1= [tex]\sqrt{ (x+3)2+(y-4)2}[/tex] .
The distance between a point (x,y) and the point (0,0) is
d2= [tex]\sqrt{x2+y2}[/tex] .
You know what y is from the equation of the line, so substitute that, set d1=d2, and solve for x.
The coordinates of the point on the straight line y=3x+1 that is equidistant from the origin and (−3, 4) is (-33/18, 39/6)
The distance formula is expressed as:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\[/tex]
For the coordinate point (x,y) to (-3, 4), the distance is expressed as:
[tex]D_1 = \sqrt{(x+3)^2+(y-4)^2}\\[/tex]
For the coordinate point (x,y) to (0, 0), the distance is expressed as:
[tex]D_2=\sqrt{(x-0)^2+(y-0)^2}\\D_2 = \sqrt{x^2+y^2}[/tex]
Since the distance are equidistant, then D1 = D2
[tex]\sqrt{(x+3)^2+(y-4)^2} = \sqrt{x^2+y^2}\\ (x+3)^2+(y-4)^2 = x^2+y^2\\x^2+6x+9+y^2-8y+16 = x^2+y^2\\6x+9-8y+16=0\\6x-8y+25=0[/tex]
Substitute y = 3x+1 and get x
6x - 8y + 25 = 0
6x-8(3x+1) - 25 = 0
6x -24x-8-25=0
-18x-33 = 0
-18x = 33
x =-33/18
Sincey= 3x + 1
y = 3(33/18) + 1
y = 33/6 + 1
y = 39/6
Hence the required coordinates is (-33/18, 39/6)

What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given expression will be solved as below:-
5x = 3x
Multiply both sides of the expression by (1/x ).
( 1/x ) 5x = ( 1/x )3x
5 = 3
Divide both sides by x.
5x = 3x
5x / x = 3x / x
5 = 3
Therefore, multiply/divide both sides by the same variable expression. The correct option is D.
