Answer:
f(-5) = -16
Step-by-step explanation:
f(x)=2x-6
f(-5) = (2 * -5) -6 = -10 - 6 = -16 ... replace x with -5
Answer: 7 and 1 sevenths
Step-by-step explanation:
turn them to improper fractions and you get 40/7 x 5/4
then cancel out to make it easier it would then look like this 10/7 x 5/1
now solve
10 x 5 is 50
7 x 1 is 7
50/7 is your answer but you need to change it by solving 50 divided by 7
your final answer is 7 and 1 sevenths
So assuming scaled down it is
1:1.5 or
2:3
so
72 is the 3 units
divide 72 by 3
72/3=14
14 times 2=28
the surface area=28 in^2
