2x+6 = 20
take 6 from both sides
2x = 14
divide by 2 on both sides
x = 7

A 12-foot flagpole casts a nine-foot shadow. What is the measure from the top of the shadow to the top of the flag pole?

amm1812

Here is the answer OwO:

A 12-foot flagpole casts a nine-foot shadow. The measure from the top of the shadow to the top of the flag pole is 15.

Here is the explanation/work OwO:

Switch sides.

c^2=12^2+9^2

12^2=144

c^2=144+9^2

9^2=81

c^2=144+81

Add the numbers: 144 + 81 = 225

c^2=225

For x^2 = f(a) the solution is √f(a)

c = 15

Therefore, your answer will be 15.

In the equation 2y=18, determine which property of equality will be used to isolate the variable. Choose the best answer. A. Mul

mixer [17]

Answer:

(C) Division Property of Equality

Step-by-step explanation:

Looking at the equation $2y=18$ , we see that if we want to isolate y, we need to divide it by 2 - because we're multiplying it by 2, and 2 times a number divided by 2 is just the number.

The Division Property of Equality states that if we have an equation, $a=b$ , then $a\div c = b\div c$ .

So, that means $2y\div 2$ will be equal to $18 \div 2$ , which is 9.

Hope this helped!

CAN SOMEONE JUST PLEASE ANSWER THIS ASAP FOR BRAINLIEST!!’

ANSWER

The three expressions are

$V = 2(9 - {b}^{3} )(9 + {b}^{3} )$

EXPLANATION

We were given the volume in cubic units to

$V = 162 - 2 {b}^{6}$

If we factor 2, we get,

$V = 2(81 - {b}^{6} )$

The expression in parenthesis is a difference of two squares. But you may not recognize it at first sight.

$V = 2( {9}^{2} - ({b}^{3})^{2} )$

This further gives us.

$V = (2)(9 - {b}^{3} )(9 + {b}^{3} )$
