Find the volume of a rectangular prism with the width of x-1, a length of x+1 and a height of 2x-3.
Answers
Answer:
The Volume is equal to 2x^3-3x^2+2x-3
Step-by-step explanation:
Formula for the volume of a rectangular prism is V=WHL
We know that:
W=x-1
L=x+1
H=2x-3
So, V= (x-1)(x-1)(2x-3)
Simplify
(x^2+1)(2x-3)
2x^3-3x^2+2x-3

If Danny gains 40 yards on the football field and then looses 15, What was the end result?
Answers
Answer:
25 yards
Step-by-step explanation:
Subtract 15 from 40.
Hope this helped :)
Answer:
25 yards
Step-by-step explanation:
Arithmetics
Imagine a straight line divided into 1-yard marks.
Danny runs for 40 marks and locates at mark 40.
He later loses 15 yards and his new position is 40 - 15 = 25 yards
Therefore, the end result is that Danny is at the 25-yard mark.

Answers
Answer: $70.49
Step-by-step explanation:
Cost of gasoline = $2.75 per gallon
Cost of diesel fuel = $3.02 per gallon.
Since Gabriel needs to purchase 15.2 gallons of gasoline for his truck, the amount spent on gasoline will be:
= 15.2 × $2.75
= $41.80
Since he needs to spend 9.5 gallons of diesel fuel for his tractor, the amount spent on diesel fuel will be:
= 9.5 × $3.02
= $28.69
Total cost spent will be:
= $41.80 + $28.69
= $70.49

Answers
Okay!
Whenever a line is parallel to another, that means they ALWAYS have the same slope!
So the slope of our new line is -2 as well !
Now let's use point C (2, 8) to find the y-intercept!
This is easy! All we need to do is plug the point in our new equation!
Remember that in point C, 2 = x and 8 = y
Time to plug in all these numbers in y = mx + b
8 = -2 (2) + y intercept
→ the 8 is in the y's place
→the -2 is in the slope place
→2 is in the x place
Now we solve for the y-intercept using basic math!
8 = -2(2) + y-intercept
8 = -4 + y-intercept
8 + 4 = y-intercept
We did it! We found the y-intercept
The y-intercept is 12!
Now let's create our final equation ...
y = -2x + 12
Find the x-intercept:
- 4x = 3y - 12

Simplified: 9x - 16
Step-by-step explanation:
2x - 11 + 4x + 7 + 3(x-4) becomes 2x - 11 + 4x + 7 + 3x -12
Group like terms, then combine to simplify:
2x + 4x + 3x -11 + 7 - 12
2x + 4x + 3x = 9x
-11 -12 + 7 = =23+7= -16
Simplified expression: 9x - 16

5a. ΔGKM ~ ΔSPM by SAS

Step-by-step explanation:
5a. Yes, the triangles are similar.
<KMG ≅ <PMS (vertically opposite angles)
ΔGKM ~ ΔSPM by SAS
Ratio: GM:SM OR KM:PM
3:6 OR 2:4
1:2 OR 1:2
Ratio: 1:2
b. No, the triangles are not similar
ΔABC is not similar to ΔDEF
Ratio: AC:DF OR AB:DE
4:6 OR 2:4.5
1:1.5 ≠ 1:2.25
Ratio: not similar
6. let the missing side of the triangle be represented by x. Since the triangle is a right angled triangle, then applying the Pythagoras theorem we have;
[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj2/^{2}[/tex]
[tex]/12/^{2}[/tex] = [tex]x^{2}[/tex] + [tex]/10/^{2}[/tex]
144 = [tex]x^{2}[/tex] + 100
[tex]x^{2}[/tex] = 144 - 100
= 44
x = [tex]\sqrt{44}[/tex]
= [tex]\sqrt{4 *11}[/tex]
= 2[tex]\sqrt{11}[/tex]
x = 2[tex]\sqrt{11}[/tex]
The missing side is 2[tex]\sqrt{11}[/tex].
Which ordered pair is a solution of the equation y+1=3(x-4)
Answers
Step-by-step explanation:
When x = 4 and y = -1,
(-1) + 1 = 3(4 - 4) = 0.
Hence (4, -1) is an ordered pair.
When x = 5 and y = 2,
(2) + 1 = 3(5 - 4) = 3.
Hence (5, 2) is an ordered pair.
Therefore the answer is C.

The polynomial x^4+px^3+qx^2+rx+6 is exactly divisible by each of (x-1), (x-2) and (x-3).
Find the values of p, q and r.
Answers
The remainder theorem says that a polynomial f(x) has a remainder of f(c) upon getting divided by x - c. So if
f(x) = x⁴ + p x³ + q x² + r x + 6
is divisible by x - 1, x - 2, and x - 3, then we have
f (1) = 7 + p + q + r = 0
f (2) = 22 + 8p + 4q + 2r = 0
f (3) = 87 + 27p + 9q + 3r = 0
Solve the system for p, q, r. You can eliminate r by substituting the first equation into the other two:
p + q + r = -7
8p + 4q + 2r = -22 → 6p + 2q - 14 = -22 → 3p + q = -4
27p + 9q + 3r = -87 → 24p + 6q - 21 = -87 → 4p + q = -11
Eliminate q by adding (-1) times the first equation to the second one, then solve for p :
- (3p + q) + (4p + q) = - (-4) + (-11)
-3p - q + 4p + q = 4 - 11
p = -7
Solve for q :
3p + q = -4 → 3 (-7) + q = -4 → q = 17
Solve for r :
p + q + r = -7 → -7 + 17 + r = -7 → r = -17
