Answer:
x=√-5
Step-by-step explanation:
8-3x=√(4x^2+20)+8
-8 -8
-3x^2=√(4x^2+20)^2
-3x^2=4x^2+20
-4x^2=20
divide both sides by -4
x^2=-5
√(x^2)=√-5
x=√-5
Rewrite the equation so that it does not have fractions
2-3/4x = 5/12
Do not use decimals in your answer.
Answer:
[tex] \frac{2 - 3}{4x} = \frac{5}{12} \\ 4x(5) = 12(2 - 3) \\ 20x = 24 - 36 \\ 20x = 12[/tex]

Factor the expression by the greatest common factor
Answer:
2(8w + 1)
Step-by-step explanation:
Look on either side of the plus sign. What ever you see that is common is a common factor. In this case it is also the greatest common factor.
2 appears on both sides of the plus sign.
2(16w/2 + 2/2)
Hello.
Remember that factoring is the opposite of distributing.
Factoring looks like this:
ab+ac=a(b+c) [tex]\longmapsto[/tex] factor out the greatest common factor
In this case, the Greatest Common Factor is
2
Now, divide both terms of the expression by 2.
2(8w+1)
Is this right? We can easily check by using the Distributive Property and distributing 2. Then, we can compare both expressions and see if we ended up with the original expression.
16w+2
See? We have the original expression.
I hope it helps.
Have an awesome day.

find the lateral area of the figure geometry
Answer:
A) 420 in²Step-by-step explanation:
The lateral surface area excludes the area of top and bottom faces.
Given is the right pentagonal prism with side length of 7 in and height of 12 in.
The lateral area is:
L = Ph = 5*7*12 = 420 in²Correct choice is A
Using the following figure, determine the measure of.
Answer:
x=36
Step-by-step explanation:
Assuming both shapes are the same, we know the entire angle is 108. Basically we just divide 108 with 3 and you have your answer (36).
Bananas cost $0.50 each, and apples cost $1.00 each.
(a) Elena would like to spend exactly $3.50 on buying fruits. If she buys 1 banana, how
many apples can she buy?
(b) Is it possible for Elena to buy 2 bananas, if she wants to spend exactly $3.50? Why or
why not?
Answer:
(a) 3 apples (b) no
Step-by-step explanation:
(a) 1 bannana = 0.50
3 apples = 3.00
total = 3.50
(b) Not possible because 2 bannanas = 1 dollar 3 bananas = 1.50 then 1.50 + 2.00 apples = 3.50

Find the length and width of rectangle CBED, and calculate its area.
Answer:
170 units
Step-by-step explanation:
60+60+25+25=170
The 60 and 60 can be found by adding the length, 20+35+5.
The 25 and 25 can be found by taking 55+8-(30+8) for the widths.
Answer:
Step-by-step explanation:
Length = DE =OP
OP = 5 + 20 + 35 = 60 ft
Length of the rectangle CBED = 60ft
Width CD = CJ - (DG +GJ)
= 55 - (8 + 30)
= 55 - 38
= 17 ft
Area of CBED = length * width
= 60 * 17
= 1020 ft²

I have a test tomorrow! I am trying to study. I have no clue what the difference between scale and scale factor is! How do you find them? I have to know in 20 min. Please HELP!!!
Answer:
they are similar
Step-by-step explanation:
a scale is a normal number scale while a scale factor is a scale but instead of normal numbers it uses factors
Let's see
Scale usually denotes unit rate or a numerical value change mentioned above graphs
1in=3ft.1cm=1mScale factor is same but it uses factors .

Cat food 'B'. If there
are 500 cats who like
Cat food 'A', how many
like Cat food B?
Answer
-
95
28
90
Answer: 90
Step-by-step explanation:
To easily solve this, just take .18 x 500. We know we can convert a percent to a decimal by moving the decimal point two places to the left. This allows us to multiply .18 x 500 to get a final answer of 90

Step-by-step explanation:
by factoring, you take whatever is on the outside and multiply by each of the inside, so.
7x-6=-42
and
-4nx-6= 24n (since we multiply 2 negatives, it becomes positive)
Answer:42-24n
