The length of a rectangular mailing label is
1 answer:
P = 2(L + W)
P = 22
L = 2W - 4
22 = 2(2W - 4 + W)
22 = 2(3W - 4)
22 = 6W - 8
22 + 8 = 6W
30 = 6W
30/6 = W
5 = W.....width is 5 cm
L = 2W - 4
L = 2(5) - 4
L = 10 - 4
L = 6....length is 6 cm

Step-by-step explanation:
take the test
We were given;
f(x) = x² + x + 2
and
g(x) = 2x + 5
f(g(x)) = f(2x+5)
= (2x+5)²+(2x+5)+2
Expanding brackets gives;
=(2x)²+2(2x)(5) +5²+(2x+5)+2
Simplifying gives;
= 4x² +20x+25+ 2x+5+2
f(g(x))= 4x² +22x +32
