Answer:

62 sq units

Step-by-step explanation:

Area of top and bottom rectangles =

2(5x3) = 15 x 2 = 30

Area of front facing and back facing rectangle =

2(2x5) = 2 x 10 = 20

Area of side facing rectangles =

2(2x3) = 2 x 6 = 12

Total surface area = 30+20+12 = 62

If my answer is incorrect, pls correct me!

The area of a rectangle is 44m. The height is 11/3m. What is the length?

iogann1982 [59]

Width of the rectangle is 12m

<u>Explanation:</u>

<u></u>

Area of rectangle = 44m

height = $\frac{11}{3}m$

area of rectangle = length X breadth

$44 = \frac{11}{3} X b\\b = 12m$

Therefore, width of the rectangle is 12m

What are the factors in the expression 4x(3x^2+5y)?

Bess [88]

4x(3x²+5y) expand by distributing terms

4x*3x²+4x*5y take out the constants

(4*3)xx²+4x*5y simplify 4*3 to 12

12xx²+4x*5y use product rule=xᵃxᵇ=xᵃ+ᵇ, and change the two variables (the x's) into ones, because if there is just one variable with no number by it, then it is a one.

12x¹⁺²+4x*5y and simplify 1+2 to 3.

12x³+4x*5y finally simplify 4x*5y to 20xy

12x³+20xy

Hope this helps, now you know the answer and how to do it. Stay healthy and safe and HAVE A BLESSED AND WONDERFUL DAY! :-)
