A rectangular painting has a length of 8 inches and an unknown width, w. The area of the painting is less than 64 square inches.

Kipish [7]

Answer:

The inequality which represents the possible values of w is w < 8.

Step-by-step explanation:

A rectangle has two dimensions, the length(l) and the width(w).

The area of a rectangle is:

$A = lw$

In this question, we have that:

$l = 8, A < 64$

So

$lw < 64$

$8w < 64$

$w < \frac{64}{8}$

$w < 8$

The inequality which represents the possible values of w is w < 8.

Express the area of a rectangle with length 7ab and width 2a as a monomial area = _____

tatyana61 [14]

The area is the product of the length and width.

... Area = (7ab)×(2a) = (7×2)×(a×a)×(b)

... Area = 14a²b

Use the properties of exponents to solve for each

ololo11 [35]

Step-by-step explanation:

$\because \: {a}^{m} . {a}^{n} = {a}^{m + n} \\ \therefore \: {4}^{8} . {4}^{2} = {4}^{8 + 2} = {4}^{10} \\ \\ \because \: ({a}^{m})^{n} = {a}^{m \times n} \\ \therefore \:({2}^{4})^{5} = {2}^{4 \times 5} = {2}^{20} \\ \\ {5}^{6} = 5 \times 5 \times 5 \times 5 \times 5 \times 5 = 15625$
