Answer:
(1, 4).
Step-by-step explanation:
For a counterclockwise rotation of 90 degrees:
(x, y) -----> (-y, x) so:
Y' (4, -1) ------> (1, 4).
12+85% is $22.20
80%x12=9.6
5%x12=0.6
9.6+0.6=10.2
12+10.2=22.20
<u><em> Answer: $22.20 </em></u>

Answer: width = 4 and length = 10
Step-by-step explanation:
Width = w and length = w + 6
2(w) + 2 (w + 6) = 28
2w + 2w + 12 = 28
4w = 28 - 12
W = 16/4
W = 4 (width)
Length = w + 6
4 + 6 = 10
Answer:
AC = 12x + 20
Step-by-step explanation:
Combine the terms:
AB + BC = AC
AB = 8x + 2
BC = 4x + 18
Plug in the corresponding terms to the corresponding variables:
(8x + 2) + (4x + 18) = AC
AC = 8x + 4x + 18 + 2
AC = 12x + 20
12x + 20 is your answer for AC.

Distributive property
We have that the distributive property states that the multiplication is done for all the terms inside the parenthesis. Then we have:
Since
3 · 28 = 84
and
3 · □ = 93
Since 3 · 31 = 93, then
□ = 31
