The length of a rectangle is twice its width. The Perimeter is 42 cm. Find the length of each side.
Answer:
A) L = 2*W
B) 2L + 2W = 42
We'll put Equation A) into B)
2*2W + 2W = 42
4W + 2W = 42
6W = 42 cm
Width = 7 cm
Length = 14 cm

factorise 35x^2-x-12
Answer:
(5x - 3)(7x + 4) .
Step-by-step explanation:
35x^2 - x - 12
= 35x^2 - 1x - 12
Now we multiply the first coefficient by the last:
35 * -12 = -420.
We need 2 values whose product is -420 and whose sum = the coefficient of x ( -1).
These are 20 and -21, so we rewrite the original expression as:
35x^2 + 20x - 21x - 12 Now we try to factor by grouping
5x(7x + 4) - 3(7x + 4) 7x + 4 is common so we have:
(5x - 3)(7x + 4) (answer).

The rabbit population in a certain area is 200% of last year's population. There are 300 rabbits this year. How many were there last year?
Answer:
There were 650 rabbits last year
The percentage of a quantity can be found by first changing the percent into a fraction and then multiplying it to the value of that quantity. Last year the number of rabbits was 150.
What is percentage?A percentage is a value that indicates the hundredth part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The population of rabbit this year is 300.
The percentage of the population with respect to the last year is 200%.
Suppose the population of rabbits last year was P.
Then as per the question, following expression can be written,
200% of N = 300
⇒ (200 / 100) × N = 300
⇒ 2N = 300
⇒ N = 150
Hence, the population of the rabbits last year was 150.

One rectangle measures 2 units by 7 units. A second rectangle measures 11 units by 37 units. Are these two figures scaled versions of each other? If so, find the scale factor.
Answer:
No.
Step-by-step explanation:
If they are scaled versions of each other then the ratio of corresponding sides would be equal.
11/2 = 5.5
37/7 = 5.29
So they are not scaled versions
Answer:
no

Answer:
M<GEF=30
M<DEF=40
Step-by-step explanation:
First you want to solve for x. to do that you put both of the equations together and make it equal to 70 since M<GED=70. so you would get 2x+10+5x-10=70.
when you solve that you get x=10. next you substitute x with 10 in the other equations to solve for the unknown measure angle. So M<GEF=2(10)+10 and M<DEF=5(10)-10. When you solve that you get M<GEF=30 and M<DEF=40. you can check this by adding them together and they add up to 70 which is the M<=GED.

Think about the system associated with the equation –x2 + x + 6 = 2x + 8. Which graph represents the system?
Answer:
Step-by-step explanation:
Set each equation equal to y, then graph each equation.
y = -x² + x + 6 (parabola)
y = 2x + 8 (line)
Notice that the system has NO SOLUTION because the parabola and the line never intersect.

Solve for x in the diagram below? Please!!!! I only have a couple more minuets left
Answer:
x = 40 degrees
Step-by-step explanation:
The line at the angle adds up to 180 degrees because it is straight, so we have the equation 100 + 2x = 180
Equation:
100 + 2x = 180
2x = 80
x = 40

80% of the students in Lea’s class earned an A or a B on the weekly math test. If 20 students got an A or a B, how many students are in Lea’s class?
20 is 80% of what number?
20 × 4 = 80, so 100 × 4 = 400 students
20 + 60 = 80, so 100 + 60 = 160 students
80 ÷ 4 = 20, so 100 ÷ 4 = 25 students
80 – 60 = 20, so 100 – 60 = 40 students
Answer:
80 ÷ 4 = 20, so 100 ÷ 4 = 25 students
Step-by-step explanation:
Is means equals to and of means multiply
20 = 80% * N
20 = .80 N
Divide each side by .8
20 / .8 = N
25 = N
there are 25 students
