-2(10r + 4) + 10(7r + 2)

Answers

Answer:

$\large\boxed{-2(10r+4)+10(7r+2)=50r+12}$

Step-by-step explanation:

$-2(10r+4)+10(7r+2)\qquad\text{use the distributive property}\ a(b+c)=ab+ac\n\n=(-2)(10r)+(-2)(4)+(10)(7r)+(10)(2)\n\n=-20r-8+70r+20\qquad\text{combine like terms}\n\n=(-20r+70r)+(-8+20)\n\n=50r+12$

The answer would be 50r+12

-2(10r+4)+10(7r+2)

Remove parentheses

-20r-8+70r+20

Collect like terms

50r+12

Find the area of the shaded region. Round your answer to the nearest tenth.area: about ___ m2

Answers

The area of the shaded region, to the nearest tenth, is about: 17.4 m².

Area of a Square

Area of a rectangle = s².
s is the side length.

Area of Circle

4 quarter circles equals a full circle.
Area of a full circle = πr².

There are four quarter circles in the diagram given, therefore:

Area of the shaded region = area of square - area of full circle

= 9² - π(4.5²)

= 17.38.

Therefore, the area of the shaded region, to the nearest tenth, is about: 17.4 m².

Learn more about area on:

brainly.com/question/13515841

Answer:

Area= about 17 m²

Step-by-step explanation:

We are given a square of length 9 m

Inside the circle we are given 4 quarter circles at the four corners

Radius of circle= 9/2 m=4.5 m

Shaded area= area of square-area of 4 quarter circles

= area of square- area of a circle

(since 4 times of a quarter equals 1)

= 9×9- π×4.5×4.5

= 81-63.585

= 17.415 m²

Area: about 17 m²
