Answer:
Expression:
Factorise the expression:
<u>Numerator:</u>
x^2 - 8 - 9
Find a pair of factors of c, that summed, make b. And decide whether the numbers are positive or negative.
1 * 9 = 9
-1 * 9 = -9
1 * -9 = -9
-1 * -9 = 9
1 + 9 = 10
1 - 9 = -8
-1 + 9 = 8
-1 - 9 = -10
The factors are
(x+1) and (x-9)
<u>Denominator</u>
5x^2 - 45x
Remove the factor here is visible - 5x.
Divide the expression by 5x.
5x(x - 9)
Both expressions have a common factor - (x - 9). This will cancel out.
Now you're left with:
(x+1)/5x

Answer:
Step-by-step explanation:
Since each fret marker is in the shape of a parallelogram, we would determine the area of each of the bottom fret markers by applying the formula for determining the area of a parallelogram. It us expressed as
Area = base × height
Each of the three bottom fret markers has a base that measures 52.5mm and a height of 6mm. Therefore, area of each the bottom fret markers is
52.5 × 6 = 315
Using proportions, it is found that:
- Peter is walking at a rate of 3 km/h.
- MJ is biking at a rate of 9 km/h.
---------------------------
- Peter is walking at a rate of x km/h.
- MJ is biking 6 km/h faster than Peter, thus 6 + x km/h.
- Opposite directions, thus, their distance increases at a rate of (6 + 2x) km each hour, as
.
6 + 2x km each hour, 18 km after 1.5 hours, thus, the rule of three is:
1h - (6 + 2x) km
1.5h - 18 km
Applying cross multiplication:
Then:
- Peter is walking at a rate of 3 km/h.
- MJ is biking at a rate of 9 km/h.

Ok so your first step is to make this an equation
she gets paid x amount per hour and she works for 22 hours
so 22x plus her bonus
22x + 500 =1204
so now solve the equation
subtract both sides by 500
22x +500 =1204
-500 = -500
to get
22x = 704
now divide both sides by 22
x = 32
