Help me answer this math

See below.

Step-by-step explanation:

The lines on the sides of the figure represent congruency. We'll solve x first by taking the lines with the values x + 6 and 2x + 4. Since they are congruent, they are equal.

2x + 4 = x + 6

x + 4 = 6

x = 2

Now that we know that x is equal to 2, we can solve for the two congruent lines at the top.

y - 4 = x + 5

y - 4 = (2) + 5

y - 4 = 7

y = 11

Now you can substitute those values to find the side lengths.

y - 4 = 11 - 4 = 7

x + 5 = 2 + 5 = 7

2x + 4 = 2(2) + 4 = 4 + 4 = 8

x + 6 = 2 + 6 = 8

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
