Answer:
The answer is 1st point, 1/2×22.0×23.1
Step-by-step explanation:
You can let XY be the base and XZ be the height of the triangle. Then, by using the formula of the area of triangle, A=1/2×base×height to find the expression.
F(x)=2x^2-10
f(5)=2(5^2)-10
f(5)=2(25)-10
f(5)=50-10
f(5)=40
Just from the figure,
As x decreases, y approaches 0
As x increases, y increases without bound
Answer:
16 cm^2
Step-by-step explanation:
Formula = 1/2 * base * height
1/2 * 8 * 4 = 16
16 cm^2
Answer:
x = 1
Step-by-step explanation:
We know that the two angles must be equal to each other. So:
65x - 12 = 43x + 10
First add 12 to both sides:
65x - 12 + 12 = 43x + 10 + 12
65x = 43x + 22
Then subtract 43x from both sides:
65x - 43x = 43x - 43x + 22
22x = 22
x = 1
