solve the equation by factoring
plssss hell
Answer:
x = {-5, 4}.
Step-by-step explanation:
2x^2 + 2x - 4 = 36
2(x^2 + x - 2 = 18)
x^2 + x - 2 - 18 = 0
x^2 + x - 20 = 0
(x + 5)(x - 4) = 0
x = -5, 4.

Three girls share 12 000 in the ratio 2:3:7.Calculate how much each girl will get
Answer:
1st girl- 2000
2nd girl- 3000
3rd girl- 7000
Step-by-step explanation:
1) add the ratio given: 2+3+7=12
2) the answer that you get is the whole and it is equal to the total: 12/12=12000
3) so now you'll simplify to get the share of each girl: 12/12=12000, what about 2/12(for the first girl)
12/12=12000, what about 3/12(for the 2nd girl)
12/12=12000, what about 7/12(for the 3rd girl)
4) after getting the answer for each, you can add their shares to see if they are equivalent to the total share

A rabbit weighed 4 ounces when it was born. The rabbit gained 2 ounces each week for the next 12 weeks. Which equation models the weight of the rabbit, w, x weeks after it was born, where x ≤ 12?
Answer: w = 2x + 4
Step-by-step explanation: The rabbit started at 4 ounces, and gained two each week.
Week 0 = 2(0) + 4 = 4
Week 1 = 2(1) + 4 = 6
Week 2 = 2(2) + 4 = 8
Week 3 = 2(3) + 4 = 10

!!!Please help will give the brainliest, and please do not put in a silly answer because you want some points or I will report you!!! What are the properties for each of these shapes and please be specific for each, a kite, trapezoid, square, rectangle, parallelogram, rhombus?
Answer:
The properties of trapezoid apply by definition (parallel bases).
The legs are congruent by definition.
The lower base angles are congruent.
The upper base angles are congruent.
Any lower base angle is supplementary to any upper base angle.
The diagonals are congruent.The bases are parallel by definition.
Each lower base angle is supplementary to the upper base angle on the same side.
A jar contains x quarters and y nickels. The jar contains $5.45. What linear equation represents the relationship between the number of quarters, the number of nickels, and the value of the coins in the jar?
Answer:
$0.25x + $0.05y = $5.45
Step-by-step explanation:
Recall that 1 nickel = $0.05
and 1 quarter = $0.25
Given that the jar contains x quarters and y nickels
The total amount of nickel in the jar
= $0.05y
The total amount of quarter in the jar
= $0.25x
Hence the total amount in the jar considering both nickels and quarters
= $0.25x + $0.05y
Since the jar contains $5.45
then
$0.25x + $0.05y = $5.45
This is the linear equation that represents the relationship between the number of quarters, the number of nickels, and the value of the coins in the jar

On question 1 of this review, Marcy attempted to solve for the value of x. On the left side of her equation, she simplified the terms to 5x +19 = 5(x -3) +2. What did she do incorrectly? What should she have done to simplify her answer correctly? The original question is below.
3(x+4)-2x+7=5(x+3)+2
Answer:
Step-by-step explanation:
She added 3x and -2x, getting 5x, instead of x. She needs to pay more attention to the positive/negative signs.

Survey: On free time 90 students like watching TV, 20 like watching TV but not reading, 80 like reading, 40 do not like watching TV. Question: Percent of total student like both watching televisan and reading
Answer:
50 %
Step-by-step explanation:
From the diagram attached,
Percentage of total students that like watching television = [(WnR)/μ]×100......... Equation 1
The number of students that like watching television and reading (WnR) = 70
The total number of students (μ) = 40+20+70+10
The total number of students (μ) = 140
Substitute these values into equation 1
Percentage of total students that like watching television = (70/140)×100
Percentage of total students that like watching television = 1/2(100)
Percentage of total students that like watching television = 50 %

[tex] \sqrt{1254 \times 1254} [/tex]
Answer:
√{1254×1254}=√1254²=±1254 is your answer
Step-by-step explanation:
1) Simplify 1254 × 1254 to 1572516.
[tex] \sqrt{1572516} [/tex]
2) Since 1254 × 1254 = 1572516, the square root of 1572516 is 1254.
[tex]1254[/tex]
Therefor, the answer is 1254.

x2 - 2x
Factorise this pleasee
Answer:
x(x-2)
Step-by-step explanation:
the common multiple here is the x, notice how it appears in both both terms. thus, we can factor it out of the equation going from x²-2x to x(x-2)
x(x-2)
Im assuming you meant x² - 2x but correct me if i'm wrong!
so x is common in both terms so you can take it out and factorise it.
Hope this helps!
