Answer:
4x-8 = 4x+12
Step-by-step explanation:
you multiply everything in the parentheses by what is outside of it
4(x-2) = 2(2x+6)
4(x)=4x & 4(-2)=-8 2(2x)=4x & 2(6)=12 then write the numbers as an equation:
4x-8 = 4x+12
a rectangular park has an area of 2/3 square mile. The length of the park is 2 2/3 the width of the park. What is the width of the park?
Answer: Area of the rectangular park = 2/3 square mile
Let us assume the width of the rectangular park = x
Then
The length of the rectangular park = 2 2/3 * x mile
= 8x/3 mile
Then
Area of the rectangular park = Length * Width
2/3 = (8x/3) * x
2/3 = 8x^2/3
(2 * 3)/3 = 8x^2
2 = 8x^2
x^2 = 2/8
x^2 = 1/4
x^2 = (1/2)^2
x = 1/2
So the width of the park is 1/2 feet.
hope this helps have a nice day❤️

For algebraic expression 2x4
– 5x3 + 4x. + 7, find (5)
a) Degree of polynomial
b) Number of terms
c) Constant term
d) Coefficient of x
e) Numerical coefficient of -5x3
.
Answer:
See explanations below
Step-by-step explanation:
Given the algebraic expression 2x4– 5x3 + 4x. + 7,
a) The degree is the highest power of x in the equation, from the equation we can see that the highest power of x is 4. HEnce the degree of the equation is 4
b) The terms we have are 2x^4, -5x^3, 4x and 7. In counting, we can see that we only have 4 terms in the equation hence the number of terms is 4
c) The constant term si the term without the variable x. From the equation the only term without variable x is 7. Hence the constant term is 7
d) The number attached t x is known as its coefficient. The number besides x is 4 frim the equation. Hence the coefficient of x is 4.
e) The numerical coefficient of -5x^3 is -5 since the constant value attached to x^3 is -5

A bag contains 7 pears and 3 apples. If you select 2 pieces of fruit without looking, how many ways can you get 2 pears.
Answer:
There are 2 ways, since we'd chosen 2 fruits
PROBABILITY:
([tex]\frac{2}{10}[/tex] = [tex]\frac{1}{5}[/tex]) or [tex]\frac{1}{10}[/tex]
METHOD:
In the 2 fruits we took both of them might be pears either maybe one of them can be a pear. The same is possible with the other fruit.

The table shows a linear relationship between x and y. What is the rate of change of y with respect to x.
A. -9/2
B. 2/9
C. -2/9
D. 9/2
Answer:
A. -⁹/2
Step-by-step explanation:
Using any two pairs of values form the table, say (-12, 60) and (-6, 33),
Rate of change = ∆y/∆x
= (33 - 60) / (-6 -(-12))
= -27/6
= -9/2
Rate of change = -⁹/2
The rate of change of y with respect to x is -9/2
Option A is correct
For a linear relationship, the rate of change of y with respect to x is given by the formula:
[tex]\frac{\triangle y}{\triangle x} =\frac{y_2-y_1}{x_2-x_1} \\[/tex]
From the table:
[tex]x_1=-20, x_2=-12, y_1=96, y_2=60[/tex]
Substitute [tex]x_1=-20, x_2=-12, y_1=96, y_2=60[/tex] into the equation [tex]\frac{\triangle y}{\triangle x} =\frac{y_2-y_1}{x_2-x_1} \\[/tex]
[tex]\frac{\triangle y}{\triangle x} =\frac{60-96}{-12-(-20)} \\\\\frac{\triangle y}{\triangle x} =\frac{-36}{8}[/tex]
Reduce the expression to the lowest term by dividing the numerator and denominator by 4
[tex]\frac{\triangle y}{\triangle x} =\frac{-9}{2}[/tex]
The rate of change of y with respect to x is -9/2

Which of the following accurately describes either the purpose or benefit, if any, of implementing controls in the design of an experiment? Check all that apply.
Group of answer choices
A. By controlling variables, the differences observed in the response variable can be attributed to the treatment and not some other factor.
B. There is no benefit of control in the experiment.
C. By controlling variables that may influence the response variable, we eliminate variability in the response variable.
D. By controlling variables in the experiment, we eliminate the need to have a control group.
E. By controlling variables that may influence the response variable, we reduce variability in the response variable.
Answer:
B D OR 2 4
Step-by-step explanation:
The purpose or the benefit for implementing the control in the design of the experiment should be option B and option D.
What is the control in experimental design?At the time of conducting an experiment, the control refer to an elements where it should not be changed or not be impacted by the other variables.
It is used like the benchmark or the comparsion point where the other test result should be determined.
Moreover, there is no benefit and we remove the requirement of the control group.
Hence, the option b and option d is correct.

360
180
120
60
90
Answer:
180
Step-by-step explanation:
Answer:
The answer is 180
Step-by-step explanation:
To check the answer:
Since 60 is part of a half then 60 * 60 = 120
Now we have to find the other 60 remaining from 180 because 180-120 is 60.
1/2 of 180 is 90.
90-60 = 30
if one half is equal to 90 then the other half is equal to 90.
