Answer:
D
Step-by-step explanation:
2y=10x
Divide both sides by 2.
y=5x
Now substitute this into the second equation.
A: l x w = a formula for area
l = w + 48 length
w(w+48) = 3024 substitute l with w+48
w^2 + 48w -3024=0 —solution to part A
B: w^2 + 48w - 3024 = 0 factor
(w-36)(w+84) = 0
Solutions for width = 36,-84
A width can’t be negative, so the width is 36 inches
I got the answer 18.79
I believe this is correct, Please tell me if im wrong. :)
Answer:
1. No
2. No
3. No
4. Yes
Step-by-step explanation:
Plug each option into u then solve the equation and see if the answer matches -15.
Ex. -15 = 1 -4 (2)
-15 = 1 -8
-15 = -7
-15 does not equal -7 therefore it is false. Use Pemdas to solve.
