Answer:
Step-by-step explanation:
(a). = x ( 2x + 1 ) = <em>2x² + x</em>
(b). = 2( 2x + 1 )( 5x + 3 ) = <em>20x² + 22x + 6</em>
(c). = 20x² + 22x + 6 - ( 2x² + x ) =
( 20x² - 2x² ) + ( 22x - x ) + 6 =
<em>18x² + 21x + 6</em>
Answer:
Smaller x: 1.20
Larger x: 5
Step-by-step explanation:
The zeros of a function h(x) are the values of x for whom h equals zero.
So, in your problem, we have
h (x) = (-4x -5)(-x +5)
h(x) = 0 when either(-4x+5) = 0 or (-x +5) = 0. So, we solve for both cases
Case 1
-4x+5 = 0
-4x = -5 *(-1)
4x = 5
x = 5/4
x = 1.20
Case 2
-x +5 = 0
-x = -5 *(-1)
x = 5
Answer:
b
Step-by-step explanation:
We find the slope is 1/4 by graphing the points. Then counting the slope as rise/run
The area of the shape is the same as
Area of the rectangle - Area of the semi-circle.
From the picture, the length and the width of the rectangle are 11 and 8 respectively so the area of the rectangle will be 8 * 11 = 88 unit^2.
From the picture, the diameter of the semi-circle is 8 and so the radius is 4.
Using the area of a semicircle formula:
A =
A = unit^2.
Hence, the area would be 88 - 25.12 = 62.9 unit^2
i just tried to solve this everyway i know possible when you get the answer lmk please.
