Answer:
= 150 square units
Step-by-step explanation:
Area of a right triangle is given by the formula;
1/2 bh ; where b is base and h is the height of the triangle
using Pythagoras theorem, we can find the height;
h² = 20² - 16²
h = √144
= 12 units
The base of the small triangle can also be found using Pythagoras theorem;
b² = 15² - 12²
b = √ 81
= 9
Therefore;
Area = 1/2 bh
= 1/2 × 12 × (16+9)
= 1/2 × 12 × 25
= 6 × 25
= 150 square units or 150 u²

Answer:
-9x^2-6x-1
Step-by-step explanation:
1.) Remove parantheses
-8x^2-5x-6-x^2-x+5
2.) Group like terms
8x^2-x^2-5x-x-6+5
3.) Add similar elements
-9x^2-5x-x-6+5
4.) Add similar elements
-9x^2-6x-6+5
Answer = -9x^2-6x-6+5
Have a nice day! ;)
Answer:
A
Step-by-step explanation:
We are looking for 2 numbers with a product of -35 and a sum of -2. These are -7 and 5, so the factored version would be (w + 5)(w - 7), or A.
