Answer: ?
Step-by-step explanation:
Answer:
4x^2 -34x+42
Step-by-step explanation:
(4x-6)(x-7)
FOIL
first 4x*x = 4x^2
outer 4x*-7 = -28x
inner : -6 *x = -6x
last : -7*-6 = 42
Add them together = 4x^2 -28x-6x +42
=4x^2 -34x+42
Mel took 8 more strokes b/c
-6+6=0
0+3=3
6+3=8 or
-6+8=3
1 x 20
2 x 10
4 x 5 (these go the other way round as well, like 10 x 2, etc)
all factors of 20 = 1,2,4,5,10,20
hope this helps!
Since they are congruent rectangles, they have the same side lengths.
The area of a rectangle is width times height
11(18)=198 square inches.
