3y^2 + 12 = 96
Subtract 12 from each side
3y^2 = 84
Divide each size by 3
y^2 = 28
Find the square root of each side
y = sqrt28
y = 5.29 (rounded to the nearest hundredth)
Answer:
Step-by-step explanation:
hello :
(5y + 6)2 = 24 means : 5y+6 = √24 or 5y+6 = - √24
5y = - 6+√24 or : 5y = - 6-√24
y = (- 6+√24)/5 or y = (- 6-√24)/5
Q1 is a dime
Q2 Is a nickel
<span> If it is parallel to the hypotenuse, then the hypotenuse is twice as long. So h = 8x
Then the legs will be (8x)/sqr(2). Since the triangle is a 45-45-90
So the perimeter = 8x + (8x)/sqr(2)+ (8x)/sqr(2)
=8x+ 16x/sqr(2)
=8x+ 8xsqr2
2)if the midsegment Is parallel to a leg, then each leg = 8x and the hypotenuse = 8x sqr2
Then the perimeter is 8x + 8x + 8xsqr2
= 16x+ 8xsqr2
