Answer:
Step-by-step explanation:
The side triangles are: 352.35
Middle triangle is: 113.4
352.35 + 113.4 = 465.75
Irrational as 0.75 x 0.75 x 3.14......
Step-by-step explanation:
According to the U.S. Census Bureau, about 63% of Americans are adults (18 and over). Use the U.S. population estimate of 308 million people to calculate the number of American adults in 2010. Round to the nearest hundred thousand adults
X=6
First subtract 11 from both sides and you'll get 5x^2=180 then divide 180 by 5 which equals 36 you get x^2=36 find square root of 36 is 6
The x becomes negative because the negative sign at the start of the parenthesis distributes to everything inside parenthesis so x becomes -x and the double negative becomes +6 so that is why
