Pedro did KCF (Keychain flip)
Step 1&2 are correct as he did the process right.
So, he must of multiplied or simplified wrong
So, 4×8= 32
And 7×8=56
As you may have noticed he has gotten 20/50 instead of 32/56
Where Pedro messed up is step 3
HOPE THIS HELPER (:!
Multiply the A by -3 this will cause d to become -3d so when the two equations are added 3d and -3d will cancel off.
-1/2x + 2 = -x + 7
-1/2x + x = 7 - 2
1/2x = 5
x = 10
Answer: B. 36
The complete square is (x+6)^2. It's missing the third term, which is 36 because 6 x 6 is 36.
Answer:
B= y+2w
Step-by-step explanation:
We can see that A= y+3w, so because B is missing one of the w's, the area must be y+2w.
