We know that volume is : Base area times height .
here base is a rectangle : the length and width are : ( x+8) and ( x-3)
Area of the rectangle = length times width
= ( x+8)* ( x-3)
The volume o f the prism = base area times height
= ( x+8)( x-3) * (x-2)
Let us expand it . = ( x * x -3x + 8x - 8* 3 ) ( x-2)
= ( x^2 + 5x - 24)( x-2)
= x^2* x - 2x^2 + 5x* x - 5x* 2 - 24x -24*-2
= x^3 - 2x^2 + 5x^2 -10x -24x + 48
= x^3 + 3x^2 - 34x + 48
This is the expression for volume .
Answer:
Graph A: y = (1/2)x - 2
Step-by-step explanation:
2x−4y=8 in slope-intercept form is -4y = -2x + 8, or y = 1/2x - 2
The slope of this line is 1/4 and the y-intercept is -2. This is represented by Graph A.
Use Y=-2/3x + b
and then plug in (-7,-4)
-7 is x, so plug that in for x
Y=-2/3(-7) + b
and plug in y, -4
-4=-2/3(-7) +b
plug into calculator and then solve algebraically!
b doesn’t mean anything, it’s just what i used for the y axis, really you could use any letter
The sum of the numbers is 7.69 * 10^6
<h3>How to evaluate the sum?</h3>
The expression is given as:
(1.54 times 10 superscript 6 baseline) (6.15 times 10 superscript 6 baseline)
Rewrite properly
(1.54 * 10^6) + (6.15 * 10^6)
Factor out 10^6
(1.54 + 6.15) * 10^6
Evaluate the sum
7.69 * 10^6
Hence, the sum of the numbers is 7.69 * 10^6
