-4²

Any number repeatedly multiplied by itself has an exponent. so (-4)(-4) has an exponent of 2 while (-4)(-4)(-4) would have an exponent of 3 and be written as -4³.

Also extra tip: Negative numbers multiplied by a negative number will always be positive.

if rhombus ABCD were reflected across the x axis to create rhombus A'B'C'D', what would the measure of angle D' be?

Mrac [35]

Answer:

D.64

Step-by-step explanation:

A linear line equals up to 180

A+D=180

Substitute 116 for A

116+D=180

Subtract 116 from both sides

D=64

A reflection across the x-axis won't change the measure of an angle

The answer is 64.

Bh+hr=25 solve for r please work it out step by step

denis23 [38]

So firstly, factor out h on the left side: $h(b+r)=25$

Next, divide both sides by h: $b+r=\frac{25}{h}$

Lastly, subtract both sides by b and your answer will be $r=\frac{25}{h}-b$

How to find the pair solution to the equation

yulyashka [42]

Answer:

To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

Chicago Pizza charges $10.49 for a medium 14" pepperoni pizza and NY Pizza charges $20.99 for an x-large 18" pepperoni pizza.

olganol [36]

Answer:

A. $0.07 per square inch

Step-by-step explanation:

Chicago Pizza has a diameter of 14".

radius = diameter/2 = 7"

area = (pi)r^2 = 3.14159(7 in.)^2 = 3.14159(49 in.^2) = 153.934 in.^2

cost per sq inch = ($10.49)/(153.934 in.^2) = $0.068 per square inch

Answer: A. $0.07 per square inch
