Okay so first, area is length times width, so 1/4x*x would be first = 1/4(x^2)=64. Then area or x = 16 or -16
perimeter would be width times two plus length times two. I recommend using math papa to calculate these numbers.
The value of x is 51 degrees
1) To solve for x, is to leave the x on the left side the other variables on the right along with the constants, like this

Note that, we subtracted 5 and then divided by x.
Answer:
W=8
Step-by-step explanation:
First you divide both sides by 3 then you square root both sides getting 8
192/3=3w^2/3
64=w^2
w=8
4x−5≥7
Step 1: Add 5 to both sides.
4x−5 +5 ≥7 +5
4x≥12
Step 2: Divide both sides by 4.
4x≥12
4 4
x = ≥3
