Answer:

C. as t^2+t +t =t^4 + 9^2-3+3=9^2 = t^3 - 81 we are forced to -81 as we would be required to move t^3 first to the other side before -81 therefore if t is a perfect square of 4 and 9 is a perfect square too we can use. Since both terms are perfect squares, factor using the difference of squares formula,

a2−b2=(a+b)(a−b)where a=xand b=9.(x+9)(x−9)

Alex is 1.6 m tall and Noah is 1.5 times as tall as Alex. How much tall is Noah in centimeters?

Yanka [14]

D= difference in height

A= Alex's height (1.6m) N= Noah's height (1.5A)

Step 1:

D=N-A

substitute N= 1.5 A in for N

D= 1.5(1.6) - 1.6

D= 2.4 - 1.6

D= 0.8 m difference in height

Step 2:

Convert meters to centimeters 1 m = 100 centimeters

0.8 x 100-80cm

Noah is 80cm taller than Alex.

Hope this helps! :)
