The simplified answer to that question should be 2a^2 - 17a + 17
Answer:
99
Step-by-step explanation:
6 x 6=36
9 x 15=135
135-36=99
Answer:
<h2>A. 225 cm3</h2>
Step-by-step explanation:
The volume of a slanted prism is defined as the product between the area of its base and its height.
Remember that height is the distance from the top to the bottom, reaching that bottom with a perpendicular angle.
So, in this case, the height is 9 cm, and the area of the base is 25 square centimeter.
This means the volume is
Therefore, the right answer is A.
According to the Pythagorean theorem, the square of the hypotenuse (the longest side) of a right-angled triangle equals to the sum of the squares of the other two sides. In this case, the ladder is the hypotenuse, which equals to the distance between the bottom of the ladder and the tree + the distance we want to find (x):
5² + x² = 13²
25 + x² = 169
x² = 144
x = √144 = 12.
The distance between the ground and the top of the ladder is 12 ft.
Answer:
10.29
Step-by-step explanation:
use Pythagorean theorem
side opposite to 90 is always hypotenuse
and we know
h^2=p^2+b^2
you can put any side as perpendicular or base.
