Answer:

21

Step-by-step explanation:

Answer:

Let x rep the lenght of the shorter one

Then the longer one is 2x+1

Therefore

(2x+1) + x = 16

We now solve for x

2x + 1 + x = 16

Group and evaluate like terms

3x +1 = 16

3x = 16 -1

× = 15/3

x = 5

So the shorter one is 5 ft

The longer one is 2(5)+1= 11

Answer:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

➷ Here are the steps to solving that problem:

(2x+1)^2

=(2x+1)(2x+1)

=(2x)(2x)+(2x)(1)+(1)(2x)+(1)(1)

=4x^2+2x+2x+1

=4x^2+4x+1
