Answer: $18.75
Step-by-step explanation:
1 - 3/8 = 5/8
12 x 5/8 = 7.5
7.5 x 2.5 = 18.75
The numerical length of PR is 46
<h3>Line segment</h3>
Given the following segments
QR=2x+4
PQ = x
PR =4x -10
If Q is on line segment PR, then;
PQ + QR = PR
Substitute;
x+2x+4 = 4x - 10
3x - 4x = -10 - 4
-x = -14
x =14
PR =4x - 10
PR = 56 -10
PR =46
Hence the numerical length of PR is 46

Answer:
c^3 + c^2 - 7c + 20
Step-by-step explanation:
First, expand the expression using distributive property.
c^2(c+4) - 3c(c+4) + 5(c+4)
c^3 + 4c^2 - 3c^2 - 12c + 5c + 20
Lastly, simplify like terms.
c^3 + c^2 - 7c + 20
Answer:
domain[-5,-3)U(4,3)
range-(4,-4)
Step-by-step explanation
parentheses are used when the circle is open and brackets are used when the circle is filled in, domain is the x axis and range is the y axis
Answer:
19.
h=0, the result is 1000×2⁰ = 1000
this is the population of bacteria the excitement started with at the very beginning.
h=-3, the result is 1000×2-³ = 1000/(2³) = 1000/8 = 125
this is a calculation 3 hours backwards from the very start of the experiment, saying that if we started the experiment 3 hours earlier, this would have had to be the starting population of the bacteria so we would arrive at the same amount of population at any given time (value of h).
20.
D 25x⁶
Step-by-step explanation:
for 19 there is not more explanation. it is all ashtray in the answer.
for 20 we see that we are dealing with a square, so ask 4 sides have the same length.
one side is 5x³.
the area of a square is simply side².
so, here (5x³)² = 25x⁶
