Which pair shows equivalent expressions?
213x+2) - 23x+1
O 243x+2) = 5x+4
o 213x+4)=x+2
0 23x+4) = 2£x+8
2.
Given:
The pair of expressions in the options.
To find:
The pair that shows equivalent expressions.
Solution:
We have,
[tex]2\left(\dfrac{2}{5}x+2\right)[/tex]
By using distributive property, we get
[tex]2\left(\dfrac{2}{5}x+2\right)=2\left(\dfrac{2}{5}x\right)+2(2)[/tex]
[tex]2\left(\dfrac{2}{5}x+2\right)=\dfrac{4}{5}x+4[/tex]
So, option A is incorrect and option B is correct.
We have,
[tex]2\left(\dfrac{2}{5}x+4\right)[/tex]
By using distributive property, we get
[tex]2\left(\dfrac{2}{5}x+4\right)=2\left(\dfrac{2}{5}x\right)+2(4)[/tex]
[tex]2\left(\dfrac{2}{5}x+4\right)=\dfrac{4}{5}x+8[/tex]
So, options C and D both are incorrect.
Therefore, the correct option is B.
The correct pair of equivalents expressions is B.
Multiplication of expressions
To solve the question, one must have knowledge about the multiplication of expressions.
When you have an expression being multiplied by a value, you multiply all the terms of the expression by that value, so that:
[tex]a (x + y) = ax + ay[/tex]
Thus, performing this multiplication for all alternatives we have:
a) [tex]2 (\frac{2}{5}x + 2) = \frac{4}{5}x + 4[/tex]
b) [tex]2 (\frac{2}{5}x + 2) = \frac{4}{5}x + 4[/tex]
c) [tex]2 (\frac{2}{5}x + 4) = \frac{4}{5}x + 8[/tex]
d) [tex]2 (\frac{2}{5}x + 2) = \frac{4}{5}x + 8[/tex]
So, the only expression that correctly corresponds to the answer is that of alternative B.

Answer:
∠MNQ = 31
Step-by-step explanation:
Set ∠MNQ and ∠NQP equal to each other.
∠MNQ = ∠NQP
5c + 6 = 7c - 4
10 = 2c
c = 5
Then substitute back into ∠MNQ.
∠MNQ = 5c + 6
∠MNQ = 5(5) + 6
∠MNQ = 25 + 6
∠MNQ = 31

C warmer in Tucson than it was in Minneapolis. If the temperatures in Tucson and Minneapolis are opposites, what is the temperature in Tucson?
PLEASE ANSWER QUICK!!!!!!!!!
Answer:
[tex]T^\circ = -12^\circ[/tex]
Step-by-step explanation:
Given
Represent the temperature in Tucson with T and that in Minneapolis with M.
From the first statement, we have:
[tex]T^\circ = M^\circ - 24^\circ[/tex]
From the second, we have:
[tex]T^\circ = -M^\circ[/tex] or [tex]M^\circ = -T^\circ[/tex] --- i.e. both are opposite numbers
Required
Find T
To calculate T, substitute -T for M in [tex]T^\circ = M^\circ - 24^\circ[/tex]
This gives:
[tex]T^\circ = -T^\circ - 24^\circ[/tex]
Collect Like Terms
[tex]T^\circ +T^\circ =- 24^\circ[/tex]
[tex]2T^\circ =- 24^\circ[/tex]
Make T the subject
[tex]T^\circ =- 24^\circ/2[/tex]
[tex]T^\circ = -12^\circ[/tex]
Hence, the temperature in Tucson is [tex]-12^\circ[/tex]

A shoe store marks up its merchandise by 38%. What was the selling price of a pair of shoes whose wholesale price is $24.50?
Answer:
SP = $33.81
Step-by-step explanation:
Given that,
The wholesale price of a shoe = $24.50
A shoe store marks up its merchandise by 38%.
We need to find the selling price of a pair of shoes. It can be given by :
SP = wholesale price + 38% of wholesale price
[tex]SP=24.5+38\%\times 24.5\\\\=24.5+\dfrac{38}{100}\times 24.5\\\\=\$33.81[/tex]
So, the selling price of a pair of shoes is $33.81.
Graph quadrilateral abcd whose vertex matrix is shown below. Then graph the dilation of quadrilateral abcd with a scale factor of 3 on the same coordinated grid. Quadrilateral abcd with vertex matrix -1 5 5 -4
2 5 3 -1
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, translation, rotation and dilation.
Dilation is the increase or decrease in size of an object.
Given the vertex matrix of quadrilateral ABCD as:
[tex]\left[\begin{array}{cccc}-1&5&5&-4\\2&5&3&-1\end{array}\right][/tex]
Therefore the vertex of quadrilateral ABCD is at A(-1, 2), B(5, 5), C(5, 3) and D(-4, -1).
Quadrilateral ABCD is dilated by a scale factor of 3 to produce quadrilateral A'B'C'D'.
Hence, the vertex matrix of quadrilateral A'B'C'D' is:
[tex]3\left[\begin{array}{cccc}-1&5&5&-4\\2&5&3&-1\end{array}\right]=\left[\begin{array}{cccc}-3&15&15&-20\\6&15&9&-3\end{array}\right][/tex]
Therefore the vertex of quadrilateral A'B'C'D' is at A'(-3, 6), B'(15, 15), C'(15, 9) and D'(-20, -3).
The correct option is figure A
What is the vertex of this parabola? y= 4(x + 1)2 - 6 0 (-1,-6) 0 (-6, -1) o 11,-6) 0 (-6, 1)

What formula do i use when it tells me to find the area with a given circumference? If you know please give an example as well, thank you.
Answer:
Step-by-step explanation:
A = C^2 / 4 x pi
so if the circumfernce was 10 you would square it to make it 100 and then you would do 4 x pi to get 12.57 ( rounded).
you would then just divide 100 by 12.57 = 7.96 ( rounded)
