Here are the steps required for Solving Quadratics by Factoring:
Step 1: Write the equation in the correct form. To be in the correct form, you must remove all parentheses from each side of the equation by distributing, combine all like terms, and finally set the equation equal to zero with the terms written in descending order.
Step 2: Use a factoring strategies to factor the problem.
Step 3: Use the Zero Product Property and set each factor containing a variable equal to zero.
Step 4: Solve each factor that was set equal to zero by getting the x on one side and the answer on the other side.
Example 1 – Solve: x2 + 16 = 10x
Step 1: Write the equation in the correct form. In this case, we need to set the equation equal to zero with the terms written in descending order.

rewrite the equation 12x=13-x^2
Answer:
x^2+12x-13 = 0
Step-by-step explanation:
12x=13-x^2
=>12x+x^2=13-x^2+x^2
=>x^2+12x-13 = 13-13
=> x^2+12x-13 = 0
Answer:
x² + 12x - 13 = 0
Step-by-step explanation:
12x = 13 - x²
the standard form of an equation is written starting from the variable of the highest degree to the lowest. Hence after rearranging;
0 = 13 - x² - 12x
0 = -x² - 12x + 13
In an equation, the highest degree of a variable should preferably be postive hence the equation to the left side to remove the negative sign:
x² + 12x - 13 = 0
Write an equation for the line parallel to the given line that contains C.
C(1,4); y=−3x+1
Answer:The equation of a line is y = mx + b where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. (Remember that the slope is the steepness of a line and the y-intercept is the point where the line intersects the y-axis. The x- and y-coordinates are values of the points on the line of y = 3x - 1.)

10. You currently have $40 dollars. You make $7.50 per hour at your part-
time job. If you worked 5 hours on Friday, 6 hours on Saturday, and 4 hours
on Sunday, how much money do you have in total?
Answer:
(B) $152.50
Step-by-step explanation:
Friday: 5 hours x $7.50 per hour = $37.50
Saturday: 6 hours x $7.50 per hour = $45
Sunday: 4 hours x $7.50 per hour = $30
$40 + $37.50 + $45 + $30 = $152.50
I would have (B) $152.50 in total.

Dan bought 35 pieces of candy. He gave 4 pieces to each of his friends. He only has 3 pieces left. Which equation, when solved for
X, gives the number of friends?
Answer:
35 - 4x = 3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
35−4x=3
35+−4x=3
−4x+35=3
Step 2: Subtract 35 from both sides.
−4x+35−35=3−35
−4x=−32
Step 3: Divide both sides by -4.
-4x/−4 = −32/ −4
x=8
Answer:
8 friends
Step-by-step explanation:
4 doesn't go evenly to 9 ppl so it would be 8 friends and 3 extra pieces
Jim paid a gym membership fee of $50, plus $20 per month. Jim has paid a total of $290 to thegym. Which equation matches this situation?
Answer:
50+20x=290 or 50+(20x12)=290
Step-by-step explanation:
Answer:
50 + 20m = 290
Step-by-step explanation:
The answer is 50 + 20m = 290, because Jim paid a membership fee that was $50. Then each month he paid $20 because of his new membership. Jim never paid $50 a month, that was only his starter fee, but then gradually paid $20 every month so it would be 20m. Hope this helped.

a 3 inch radius circle is drawn inside a 7 in radius Circle if you throw a dart at the circles what is the probability you land inside the smaller circles
Answer:0.82
Step-by-step explanation:
The first step is to determine the areas of the inner and the bigger circles.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
diameter = 148.4 cm
Radius = 3 inches
Area = 3.14 × 3² = 28.26 inches²
Considering the bigger circle,
Radius = 7 inches
Area = 3.14 × 7² = 153.86 inches²
The area between the bigger and inner circles is
153.86 - 28.26 = 125.6 inches²
Probability = number of favourable outcome/number of total outcome.
the probability you land inside the bigger circle but outside smaller circle is
125.6/153.86 = 0.82
Ryan's take-home pay is $2,500 each month. The amount for gas is $125. Calculate the percentage Ryan uses on gas from his take-home pay. please help!! O^O
Answer: 5%
Step-by-step explanation:
Since Ryan's take-home pay is $2,500 each month and the amount for gas is $125.
The percentage that Ryan uses on gas from his take-home pay will be:
= Amount used on gas / Take home pay × 100
= 125/2500 × 100
= 1/20 × 100
= 5%
He used 5% on gas.

what is the value of x? 26 degrees tangent lines
Answer:
154°Step-by-step explanation:
The central angle and the angle between the tangents are supplementary, so
x + 26° = 180° ( subtract 26° from both sides )
26 - 26 = 0
180 - 26 = 154
x = 154°
The value of the x will be 154°.
How to find the interior central angle?The central angle and the angle between the tangents are supplementary.
If there is a circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to line L.
So,
x + 26° = 180°
Subtract 26° from both sides;
x + 26 - 26 = 180 - 26
x = 154°
Hence, the value of the x will be 154°.

What is 12 - 33/4 equal in fraction form?
Answer:
3. 3/4
hope this helps
The expression 12 - (33/4) is equal to 15/4.
To express 12 - (33/4) as a fraction, we need to find a common denominator for the subtraction. The common denominator should be a multiple of 4, which is the denominator of (33/4).
We can rewrite 12 as an equivalent fraction with a denominator of 4:
12 = 48/4.
Now, we can rewrite the expression as:
48/4 - 33/4.
Since the denominators are the same, we can subtract the numerators directly:
(48 - 33) / 4 = 15/4.
Therefore, 12 - (33/4) is equal to 15/4.
In fraction form, the result is 15/4. This means that when we subtract 33/4 from 12, the answer can be represented as the fraction 15/4.
