The top is 4ft by 2 ft, area = 4 * 2=8 square feet.

The back is 1 1/2 ft by 4 feet, area = 1.5 *4 = 6 square feet.

The bottom equals the top = 8 square feet.

The front equals the back = 6 square feet.

The left side is 1 1/2 ft by 2 ft = 2 * 1.5 = 3 square feet.

The right side equals the left side = 3 square feet.

Total area = 8 + 6 + 8 + 6 + 3 + 3 = 34 square feet

Answer:

2. 34 ft squared

Step-by-step explanation:

The surface area for a rectangular prism is given by

A=2(wl+hl+hw)

w =1 1/2 = 1.5

l =2 ft

h = 4 ft

A = 2( 1.5 * 2 + 4*2 + 4*1.5)

= 2( 3 + 8 + 6)

= 2( 17)

= 34 ft^2

Answer:

$\frac{6}{8}$ or $\frac{3}{4}$

Step-by-step explanation:

Convert the mixed numbers into improper fractions.

$2\frac{3}{8}-1\frac{5}{8}=\frac{19}{8}-\frac{13}{8}$

Since the two fractions have the same denominator, just subtract the numerators.

$\frac{19}{8}-\frac{13}{8}=\frac{6}{8}$

If required, rewrite the fraction in simplest form.

$\frac{6}{8}=\frac{3}{4}$

Justify Reasoning Determine whether 3x + 12 + x is equivalent to 4(3 + x). Use properties of operations to justify your answer.

Orlov [11]

For 3x + 12 + x, do like terms:
4x + 12
For 4(3 + x), multiply
12 + 4x
They are both the same, just written in different ways. One is adding like terms and the other is multiplying with parentheses. Even though it may be switched around, it is still the same.

Hope this helps :)
