Answer:

(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);

Step-by-step explanation:

formula to find area is L* W = A ; meaning length multiplied by width equals to the area.

21.

using the formula to find area...

l*w=a

(7x+2)(3x-1) would be your answer

btw, don't put the "=a" at the end, since it's an expression :))

22.

since the problem states that it's a square, you can just say either...

(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts

Answer: $\dfrac{19}{40}$

Step-by-step explanation:

Given: Fraction of goal raised on first day = $\dfrac{1}{8}$

Fraction of goal raised after second day = $\dfrac35$

Now , Fraction of goal raised on second day = Fraction of goal raised after second day - Fraction of goal raised on first day

$=\dfrac35-\dfrac18\\\\=\dfrac{24-5}{40}\\\\=\dfrac{19}{40}$

Required fraction = $\dfrac{19}{40}$

Calculate the area shaded

Rudiy27

Answer:

7.722 cm^2

Step-by-step explanation:

Step 1: Find the area of the square.

Area of square = s^2, where s = side
6^2 = 36 cm^2

Step 2: Find the area of the circle.

We are given the diameter of the circle as 6 cm, so the radius must be 3 cm.
Area of circle is $\pi r^2$ , so now we plug in and simplify.
$3.142 * 3^2$
$3.142 * 9$
$28.278$

Step 3: Subtract area of circle from area of square.

$36 - 28.278$
$7.722$

Therefore, the area of the shaded region is 7.722 cm^2.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
