Answer: 1725
Step-by-step explanation: A= A+B/2 h= 50+65/2x30=1725
Given that the image was dilated by scale factor 3 then:
a] Length of the dilated side will be:
length/width=(original length/width)*(scale factor)
length=3*10=30 in
Width=3*6=18 in
thus the dimensions of the new image will be:
30 in by 18 in
b. The diagram below represent s the rectangle. 1 cm represent 10 inches
12 x 8= 96
10 x 8 =80
12 × 10= 120
120+80+96= 296

21k - 3n + 9p > 3p + 12....for n
-3n > 3p + 12 - 9p - 21k
n < (3p + 12 - 9p - 21k) / -3
n < -p - 4 + 3p + 7k
n < 2p - 4 + 7k <===
