Answer:
5
Step-by-step explanation:
We are asked to find the value of A. We know from the question that we need to have the sum of -3x and (A)x equal the third term of the original polynomial, which is 2x. written out in an equation, it looks like this.
We can simplify the equation if we add 3x to both sides, which then leaves us with this.
We can further simplify the equation by dividing both sides by x. This leaves us with our last equation for this problem.
Finally, we have our answer. We can also verify that this is a valid integer by multiplying our, now completed, quotient by the divisor and adding the remainder, which in this case, our remainder is 0, so we will not be including it in our operation.
If our calculations were all correct, the product of these polynomials should equal our dividend, verifying our integer is valid; lo' and behold, it is.
156 sq ft
explanation:
a of circle= pir^2=192
a of sq= 6*6=36
192-36= 156
Answer:
Around 11:15 am
Step-by-step explanation:
Let h represents the number of hours the plumber works
Since the plumber charges $65 fee plus $75 per hour, the bill can be calculated by:
→ bill = 65 + 75h
Since the bill is $195.25
→ 195.25 = 65 + 75h
→ 75h = 130.25
→ h = 1.74
1.74 implies that the plumber worked almost 1 hour and 45 minutes. Since the plumber started at 9:30, the repair was completed around 11:15 am.
Answer:
289in²
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a square based pyramid
Given data
Volume v= 2023 in³
Height h= 21 in
The expression for the volume of a square based pyramid is
V= a²*(h/3)
Let us solve for a which is the side of the square base
2023= a²*(21/3)
2023= a²*7
a²= 2023/7
a²= 289 (this is the area )
a= √289
a= 17in
Proof
Hence the area of the square base is
Area = a*a= 17*17= 289in²
