Answer: The answer is 148 square feet.

Step-by-step explanation:

So if we are given the information to the area of the composite figure, we just first have to find the area of the smaller shapes and then add them all together to achieve the total.

1. The larger rectangle is a 10 by 14 rectangle.

2. The smaller rectangle is a 1 by 8 rectangle.

How did I get around to 8 feet?

Subtract 3 and 3 from 14, and you'll get 8 for the side.

Now just find the areas of each of the rectangles:

1. 10 times 14 = 140

2. 1 times 8 = 8

Now add them together:

140 + 8 = 148

The answer is 148 square feet.

Christina collects stamps. She has 47 stamps in all. She has 20 stamps from europe. The number of African stamps is 2 times the

astraxan [27]

She has 47 total
20 are from Europe
some are from Africa,
and some from Asia

how many from Africa? hmm let's say "a"
how many from Asia? hmm let's say "b"

we know that, she has twice as many "a" as she has "b" stamps,
so, whatever "b" is, a = 2 * b, or a = 2b

so.. let us add them together

$\bf \begin{array}{llllllll}
20&+&a&+&b&=&47\\
\uparrow &&\uparrow &&\uparrow \\
europe&&africa&&asia\\
\downarrow &&\downarrow &&\downarrow \\
20&+&2b&+&b&=&47
\end{array}$

solve for "b", to see how many from Asia she has

what's "a"? well, a = 2b , that's how many African ones she has :)

Alexandra buys sweatshirts for $12 each. In her store, she sells each sweatshirt for $30.

serious [3.7K]

Multiply $30 by .25 you get, it's $7.50so you subtract $7.50 from $30 and you get $22.50. Then multiply 2 (sweaters) by $22.50 and you get $45,but wait you still have to multiply that sales tax so you multiply .04 by $45 and you get $1.80, later you subtract $1.80 from $45 and you get $43.20(the cost of the two sweaters) I did part1 only cuz' no I have no time left Sorry for the inconvenience
