Answer:
step 3
Step-by-step explanation:
in step 3, he wrote that the sum of 171+ 52.45-18.50 was 241.95 when it is 199.95
B. No, the rectangle cannot have x = 20 and y = 11 because x + y ≠ 32
Perimeter = 2(l + w)
Perimeter = 64
Assuming: P = 64; w = 11 ; l = ?
64 = 2(l + 11)
64/2 = l + 11
32 - 11 = l
length = 21.
Answer:
The correct answer is C.
2x² + 7x - 30 is equal to (2x−5)(x+6)
Step-by-step explanation:
2x² + 7x - 30
= 2x² − 5x + 12x − 30
= (2x−5)(x+6)
