A square has a side length of 6 inches. Which of the following is the length of its diagonal in inches

8.5

Step-by-step explanation:

The Pythagorean theorem (a^2 + b^2 = c^2) can be used to solve this problem. We have a square with a side length of 6 inches. That means all of the sides will be 6 inches. That also means the base and the height are 6 inches. Let's now cut the square in half diagonally. We have a slope now, which is the hypotenuse. Let's put these values in the Pythagorean theorem and solve for the diagonal, or the  hypotenuse:

This is equivalent to:

C = 8.5 (rounded)

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

i can answer this question sweetie!
