Answer:
area= x^2+8x+7
Step-by-step explanation:
a=l*w
l=x+7
w=x+1
a=(x+7)(x+1)
a= x^2+8x+7
Answer: w = -3u/2 + 2
Step-by-step explanation:
-12u + 13 = 8w - 3
-12u + 13 + 3 = 8w -3 + 3
-12u + 16 = 8w
w = -3u/2 + 2
X = 2y
2x + 2y = 24
So if x = 2y that means 2x = 4y. Which means that 2x + 2y = 24 can be written as 4y + 2y = 24. Simplified to 6y = 24. Now we need to get 1y so we divide both sides by 6, 6y/6 = y and 24/6 = 4. so y = 4. so x= 2y can be written as x = 8.
Answer:
x = 3/8 (but the fraction is negative.)
Decimal form if needed.
x = - 0.375
