Answer:
width = 6
length = 4
Step-by-step explanation:
perimeter = 2L + 2W
L = W - 2
plug in perimeter:
20 = 2L + 2W
you know the length is 2 less than the width
plug in (w - 2) for L:
20 = 2(w - 2) + 2w
solve for w:
20 = 2w - 4 + 2w
20 = 4w - 4
4w = 24
w = 6
now plug in 6 for w in either equation, whichever is easier to solve:
L = 6 - 2
L = 4
width = 6
length = 4
Substitute a number for each variable
Ex.
2x x=5
(2)(5)
=10
Answer:
α=39.80°
Step-by-step explanation:
applying the law of sin and cos, we have:
and to the nearest tenth of a degree
α=39.80°
There are 4 quarts in 1 gallon.
3 x 4 = 12
12 + 2 = 14 quarts
Hope this helps!! :)
