Are you solving for x or y?
Answer:
<h2>7</h2><h2 />
Step-by-step explanation:
Diagonal = ![\sqrt{2^{2} +3^{2}+6^{2} } =\sqrt{49} =7](https://tex.z-dn.net/?f=%5Csqrt%7B2%5E%7B2%7D%20%2B3%5E%7B2%7D%2B6%5E%7B2%7D%20%20%7D%20%3D%5Csqrt%7B49%7D%20%3D7)
7x + 4 + 9x = 180
16x = 176
x = 11
9x = 9x11 = 99
7x + 4 = 7(11) + 4 = 77 + 4 = 81
<span>in order to form a rectangular image, each angle needs to be equal 90 degreesn
99 - 9 = 90
81 + 9 = 90

are 30/12 and 40/16 equivilent?
if a/b=c/d then a/b times d/c=1
basically if ad=bc then they are equivilent
30/12 ad 40/16 equvilient?
30/12 times 16/40=1?
480/480=1?
1=1?
yes
they are equivilent
