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:

The correct option is commutative property.

Step-by-step explanation:

The expression that Renee is simplifying is:

$(7)\cdot(\frac{13}{29})\cdot(\frac{1}{7})$

It is provided that, Renee recognizes that 7 and $\frac{1}{7}$ are reciprocals, so she would like to find their product before she multiplies by $\frac{13}{29}$ .

The associative property of multiplication states that:

$a\times b\times c=(a\times b)\times c=a\times (b\times c)$

The commutative property of multiplication states that:

$a\times b\times c=a\times c\times b=c\times a\times b$

The distributive property of multiplication states that:

$a\cdot (b+c)=a\cdot b+a\cdot c$

The identity property of multiplication states that:

$a\times 1=a\\b\times 1=b$

So, Renee should use the commutative property of multiplication to find the product of 7 and $\frac{1}{7}$ ,

$(7)\cdot(\frac{13}{29})\cdot(\frac{1}{7})=(7\times\frac{1}{7})\times\frac{13}{29}=\frac{13}{29}$

Thus, the correct option is commutative property.

Triangle ABC is shown Translate Triangle ABC 5 units left and 4 units up and reflect it over the x-axis

tekilochka [14]

Here is my process for solving this.

First I drew arrows that indicated I was moving the whole triangle 5 units to the left.

*Look at first attachment*

Then I drew another triangle using those new points. (The new triangle is in pink)

*Look at second attachment*

Then I drew arrows that moved this new triangle 4 units up. (The new arrows are in pink)

*Look at third attachment*

Then I drew the new triangle in blue using the new points.

*Look at fourth attachment*

Then I mirrored / reflected the triangle over the x axis (the horizontal line) In green.

*Look at fifth attachment*

The fifth attachment in green is the final product! Hope that helps.
