Answer:
59/5 or 11.8
Step-by-step explanation:
4(1/5+3)-5(1/5)
4(1/5+3)-5(1/5)
-> 59/5, 11.8
Answer:
80
Step-by-step explanation:
f(3)=4(3)^3-3(3)^2+5(3)-16
f(3)=4(3*3*3)-3(3*3)+15-16
f(3)=4(27)-3(9)+15-16
f(3)=108-27+15-16
f(3)=81+15-16
f(3)=96-16
f(3)=80
We know the width of the first picture, is 4
we know the ratio from smaller to larger is 1.5:2
thus

solve for "w".
we know the length of the first picture, 6

solve for "L".
