Step-by-step explanation:
hope this helps:)
Answer:
Step-by-step explanation:
Using FOIL, we can expand the polynomial on the left-hand side of the equation:
Next, let's move all of the terms to the left-hand side of the equation and combine like terms:
Now we can factor the quadratic:
This produces two equations to give us the two solutions:
The first solution:
and the second solution:
So the solutions to this problem are
Answer:
y = 5 - 3x
Step-by-step explanation:
slope intercept form - y = mx + b
y = 5
slope/m = -3
y = 5 - 3x

3 hours = 26.25
---------------------------------
Find wages for 1 hour :
---------------------------------
1 hour = 26.25 ÷ 3 = 8.75
---------------------------------
Find wages for 8 hours :
---------------------------------
8 hours = 8.75 x 8 = $70
---------------------------------
Find wages for a week :
---------------------------------
$70 x 7 = $350
---------------------------------

---------------------------------
2 hours = $15
---------------------------------
Find 1 hour :
---------------------------------
1 hour = $15 ÷ 2 = $7.50
---------------------------------
Find 8 hours :
---------------------------------
8 hours = $7.50 x 8 = $60
---------------------------------
Find 1 week :
---------------------------------
1 week = $60 x 5 = $300
---------------------------------
Define x :
---------------------------------
Let x be the number of weeks needed
---------------------------------
Construct equation :
---------------------------------
350x = 300x + 1000
---------------------------------
Solve for x :
---------------------------------
350x = 300x + 1000
---------------------------------
Take away 300x from both sides :
---------------------------------
50x = 1000
---------------------------------
Divide by 50 :
---------------------------------
x = 20
------------------------------------------------------------------
Answer: It will take 20 weeks.

17 yards. The fence that enclose Sondra's backyard is a right triangle whose sides measuring 8 yards, 15 yards and 17 yards respectively.
The key to solve this problem is using the Pythagorean Theorem that dictates; In every right triangle the square of the hypotenuse is equal to the sum of the squares of the legs and the equation hypotenuse²=leg1²+leg2².
For this problem we know the measuring of two side, which mean that we can apply Pythagorean Theorem equation as follow:
Let's say that one of the side is a = 8yards, and the other side is b = 15yards. So, we want to know how long the third side c long.
Applying the Pythagorean Theorem:
Substituting the values of the sides a and b:
