Answer:
1/-4
Step-by-step explanation:
slope = y2-y1/x2-x1
slope = 5-3/-3-5
Slope = 2/-8
Slope = 1/-4
We set up an equation: 160/?= 20/100
Cross multiply: 20*?= 160*100
⇒ ?= 160*100/20= 800
160 is 20% of 800~
Answer:
63 cm^2
Step-by-step explanation:
p = l + w + l + w
32 = 2l + 2w
32 = 2(w + 2) + 2w
32 = 2w + 4 + 2w
32 = 4w + 4
28 = 4w
7 = w
l = w + 2
l = 7 + 2
l = 9
Check your work:
32 = 9 + 7 + 9 + 7
32 = 32
Correct
A = l × w
A = 9 × 7
A = 63
