Answer 2

Answer:

Length = 11 1/3 ft; Width = 4 2/3 ft

Step-by-step explanation:

First question:

The length is 2 more than twice the width, so

L = 2W + 2

Second question:

2L + 2W = 32

L = 2W + 2

Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.

2L + 2W = 32

2(2W + 2) + 2W = 32

4W + 4 + 2W = 32

6W = 28

W = 28/6 = 14/3 = 4 2/3

L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3

L = 11 1/3

W = 4 2/3

Answer: Length = 11 1/3 ft; Width = 4 2/3 ft

Can the exponent in the denominator be subtracted from the exponent in the numerator when the based are different? Explain

Answers

Answer:

If the higher power is in the denominator, put the difference in the denominator and vice versa, this will help avoid negative exponents and a repeat of step 3. Step 6: Raise each coefficient (or number) to the appropriate power and then simplify or reduce any remaining fractions. Step 1: Apply the Zero-Exponent Rule.

Answer:no

Step-by-step explanation:

Because u can not subtract a denominator from numerator u must subtract the denominator by the denominator
