True or false: The equation below is too complicated to use the "isolate the
radical, then square both sides" method to simplify.
Answer: False
=============================================================
Explanation:
The radical is one step away from being fully isolated. We would apply the rule that [tex]\frac{\sqrt{A}}{\sqrt{B}} = \sqrt{\frac{A}{B}}[/tex]
In this case,
[tex]\frac{\sqrt{x+3}}{\sqrt{x-1}} = \sqrt{\frac{x+3}{x-1}}[/tex]
Meaning that the equation
[tex]\frac{\sqrt{x+3}}{\sqrt{x-1}} =3[/tex]
is the same as
[tex]\sqrt{\frac{x+3}{x-1}} = 3[/tex]
From here, we square both sides and use algebra to isolate x.

Answer:
A = 12
Step-by-step explanation:
First you need to get the length from the perimeter, the formula is l= p/2 - w
After using the formula, you would get 6 for length. The formula for the area of a rectangle is a = lw, so you would multiply 6 and 2 which would give you 12 as your answer.
I apologize if I made any grammar mistakes or if it is unclear.
Answer:
I got area is 12 too
Step-by-step explanation:

First to get the question correct get's brainliest.
I calculated this myself, and I got the answer 3/4, but I'm trash at explaining long problems. So here is what I found to help explain it. It's not a link.
"If (p, r) lies on the line y = x + b, then
r = p + b…. (1)
If (2p, 5r) lies on the line y = 2x + b, then
5r = 2(2p) + b
or 5r = 4p + b…. (2)
Subtracting equation (1) from (2), we get
5r - r = 4p + b - p - b
4r = 3p or r/p = 3/4"

a school has 60 girls and 90 boys. the ratio of girls to boys
Answer:
60:90
Step-by-step explanation:
The ratio of girls (G) to boys (B) is 2 : 3.
Let the girls be represented by G.Let the boys be represented by B.Given the following data:
Number of girls = 60 girlsNumber of girls = 90 boysIn this exercise, you're required to find the ratio of girls (G) to boys (B). In order to do this, we would divide the two values to the least.
[tex]G : B = 60 : 90[/tex]
Dividing both sides by 30, we have;
[tex]G : B = \frac{60}{30} : \frac{90}{30} \\\\G : B = 2 : 3[/tex]
Therefore, the ratio of girls (G) to boys (B) is 2 : 3.

Aaron bought 7 packs of balloons for the party. There were 50 balloons in each bag. 40 of the total number of balloons were yellow. How many balloons were not yellow?
Answer:
[tex]total \: balloons = (50 \times 7) \\ = 350 \: balloons \\ none \: yellow \: balloons = 350 - 40 \\ = 310 \: none \: yellow \: balloons[/tex]
Answer:
310
Step-by-step explanation:
The equation that we would use to solve this problem is 7 × 50 - 40 = b
(b is the number of non-yellow balloons)
Since Aaron bought 7 packs of balloons with 50 balloons in each pack, we would need to multiply 7 and 50 to find the total amount of balloons that he bought.
7 × 50 = 350.
Now we subtract 40 (the total number of yellow balloons) from 350 (the total number of balloons), to find the amount of balloons that are not yellow.
350 - 40 = 310

In the following triangle, find the values of the angles Band B, which are the best approximations to the solutions to this ambiguous case?
Answer:
B. B = 70.5° or B' = 109.5°
Step-by-step explanation:
(sin 45°)/13.5 = (sin B)/18
sin B = (18 * sin 45°)/13.5
sin B = 0.9428
B = sin^-1 0.9428
B = 70.5°
B' = 180° - 70.5°
B' = 109.5°

What is the surface area of the rectangular pyramid below? B = 4.8 m
Answer:
625 unit²
Step-by-step explanation:
Surface area of a rectangular pyramid :
Area of base * 4(area of triangular side)
Area of base = length * width
Area of base = 15 * 15 = 225
Height of triangular side = 15
Area of triangle = 1/2 * base * height
Area of triangle = 1/2 *15 * 15 = 112.5 unit²
Surface area = 225 + 4(112.5)
Surface Area = 225 + 450
Surface Area = 625 unit²

help find the gradient
Answer:
gradient m = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
y = 3x - 5 ← is in slope- intercept form
with gradient m = 3
Answer:
[tex]\implies\boxed{\rm \red{ Slope (m)= 3 }}[/tex]
Step-by-step explanation:
Given :-
A equation of a line .[tex]\rm y = 3x - 5 [/tex]And we need to find out the gradient of the line . Gradient of line is nothing but the slope of the line . The given equation is in slope intercept form , so we can find out the slope by comparing .
Slope Intercept form :-
[tex]\rm\implies y = mx + c [/tex]
Here m is the slope of the line.Given equation :-
[tex]\rm\implies y = 3x - 5 [/tex]
On comparing :-
[tex]\implies\boxed{\rm \red{ Slope (m)= 3 }}[/tex]
Hence the slope of the line is 3 .

20 men can complete a piece of work in 24 days how many men should be subtracted to finish the work in 32 days?
Answer:
5 men should be subtracted.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
As these measures(number of men needed and time) are inversely proportional, we multiply the lines instead of cross multiplication.
How many men should be working to complete the work in 32 days?
20 men - 24 days
x men - 32 days
Then
[tex]32x = 20*24[/tex]
[tex]x = \frac{20*24}{32}[/tex]
[tex]x = 15[/tex]
How many men should be subtracted?
There are 20 to complete in 24 days.
15 are needed to complete in 32 days.
20 - 15 = 5
5 men should be subtracted.
