F(2)=42(2)-100
f(2)=84-100
f(2)=-16
Answer:
12.9
Step-by-step explanation:
Intersecting chord segments are proportional, so:
35×a = 15×30
a = 12.9
Answer:
(B) 18 cm x 8 cm
Step-by-step explanation:
let the length be x,
then the width is
x + 2
2(
x + 2 + x ) = 52
x + 2 + x = 26
= 24
x = (24*3)/4
x = 18
then the length is 18 cm
and width is (1/3)*18 + 2 = 8
Therefore the dimensions are length:width = 18 cm : 8 cm
Well, I am not exactly sure if this is what your asking but one foot is twelve times the size of a foot.
