Answer:
x = -1
x = 9
Step-by-step explanation:
First you have to equals the equation to zero, then you have to find two numbers that their sum equals 8 and multiplied equals -9. In this case, those numbers are -1 and 9.
After you find those numbers, you split the equation and equals each term to zero.
So the answer is x=-1 and x=9

Answer:
D
Step-by-step explanation:
The diagonals of a rhombus intersect at right angles. So sneaky!!
So the third angle of the triangle containing the two base angles is 90 degrees.
- 2x + 3 + 3x + 2 + 90 = 180 Combine like terms
- 5x + 95 = 180 Subtract 95 from both sides
- 5x = 180 - 95 Combine the terms on the right.
- 5x = 85 Divide by 5
- x = 85/5
- x = 17
Sorry i messed up at first i think it actually is 50.3

Answer:
Step-by-step explanation:
Calculate the area of the two triangles first: 6 * 16 = 96
Then the rectangle: 10 * 16 = 160
160 + 96 = 256
