The answer to 3 is C, because 18+15 is 33, and 33 divided into three equal groups would have 11 in each.
The answer to 4 is A, because in 11/3 3 can go into 11 3 times, with 2/3 remaining.
Answer:
108
Step-by-step explanation:
Because the area formula is a*b and 12*9 is 180
So the answer is 180 which is A

Assuming 2x2 is

you would get 2(2.5)(2.5) - 3(2.5) +7, which is 2(6.25) - 7.5 + 7, 12.5 - 0.5, [
12]
81.27 is the answer to 21% of 387 so a good estimate would be 82
Answer: x=7.21
Step-by-step explanation: This is a right triangle- remember the Pythagorean theorem: a² + b² = c². To find leg a, you'd use a = √(c² - b²) **leg a would be the side that is labeled with 12. To find leg b, you'd use b = √(c² - a²) *this is the equation we need. To find the hypotenuse, or <em>c</em>, you'd use c = √(a² + b²). This equation works for right triangles only.
