Please answer this for me. also please show your work. thanks

here, suppose the missing length be X

hy ^2 = (one side square )^2 +(Other side square)^2

29^2= X^2 + 21^2

841 = X^2 + 441

X^2 = 841 - 441

X^2 = 400

X = 20 taking square root both side

the value is missing side length is 20 .

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2

it contains 3 terms

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
