Answer 1

Answer: Hello,

L=2W-3
and Area= (2W-3)W=77
==>2W²-3W-77=0

==> (W=7) or (W=-22/4 to exclude <0)
If W=7 then 2*W-3=14-3=11
Area=7*11=77

Photgraphy is 7 by 11 (cm)

Solve this equation: –9h – 6 + 12h + 40 = 22. A. h = 24 B. h = – 4 C. h = 4 D. h = –4/7

Answers

In the equation: -9h - 6 + 12h + 40 = 22, collecting like terms gives: -9h + 12h = 22 + 6 - 40 which gives 3h = -12. They we divide both sides of the equation by 3 to get 3h / 3 = -12 / 3 which gives h = -4. Therefore, the solution to the given equation is h = -4 (option B).

Two ways you can evaluate 15(90-3)

Answers

15 of 90 minis 3 15 times 90 minus 3

15(90-3)
first way
15 times 90 = 135
15 times 3 = 45
135 - 45 = 90
second way
90-3 = 87
15(87) = 1305
