Rewrite the expression by factoring out (w+3).
7w2(w+3)-3(w+3)
Answer:
(w + 3) [7w² - 3]
Step-by-step explanation:
Given expression:
7w²(w + 3) - 3(w + 3);
Now rewriting the equation by factoring out (w+ 3);
Solution:
7w²(w + 3) - 3(w + 3);
= (w + 3) [7w² - 3]
The solution is (w + 3) [7w² - 3]

Help please!! Thank you!
Answer:
S
Step-by-step explanation:
The vertex is S. The angle can only be measured from point S.
Two angles are supplementary. One measures 3x-2 and the other measures 2x+7 Find the value of x and the measure of the smaller angle.
Sum of two angles that are supplementary = 180°
Then :-
[tex]3x - 2 + 2x+ 7 = 180[/tex]
[tex]5x + 5 = 180[/tex]
[tex]5x = 180 - 5[/tex]
[tex]5x = 180 - 5[/tex]
[tex]5x = 175[/tex]
[tex]x = \frac{175}{5} [/tex]
[tex]x = 35[/tex]
Which means :-
The measure of the larger angle :-
= 35 × 3 - 2
= 105 - 2
= 103°
The measure of the smaller angle :-
= 2 × 35 + 7
= 70 + 7
= 77°Therefore , the value of x = 35 and the measure of the smaller angle = 77° .

A $23.00 item with sales tax of 8%? Find the sales tax?
Answer:
Step-by-step explanation:
Tax = 8% of 23
= [tex]\frac{8}{100}*23[/tex]
= [tex]\frac{184}{100}[/tex]
= $ 1.84
Answer
The answer is $1.84
Step-by-step explanation
The formula for calculating the sales tax on a good or service is: selling price x sales tax rate, and when calculating the total cost of a purchase, the formula is: total sale amount = selling price + sales tax.

Find the value of x
(9x-38)+(4x+23)=180
Answer:
x=15
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
9x−38+4x+23=180
9x+−38+4x+23=180
(9x+4x)+(−38+23)=180(Combine Like Terms)
13x+−15=180
13x−15=180
Step 2: Add 15 to both sides.
13x−15+15=180+15
13x=195
Step 3: Divide both sides by 13.
13x/13=195/13
Answer:
15
Step-by-step explanation:
9x-38+4+23=180
13x-15=180
13x=195
x=15

math help please! - ( 2/5 )
Answer:
D
Step-by-step explanation:
it is D because you always want x to be a lone fraction and that would be the first step im 99% sure unless someone can correct me :)
Answer:
d) subtract 15 from both sides
Step-by-step explanation:
Process of elimination:
a) 2.5 and x are being multiplied, not subtracted, so (a) is wrong right off the bat.
b) you may divide 2.5 by both sides, but you want to get "x" on one side first. So you would do (b) first either.
c) to get rid of 15, which we need to somehow, we need to do the opposite operation than the one in the equation. 15 is +15, not negative, and so you would need to subtract to get rid of 15. This is why (c) is also wrong.
That leaves us, with (d), because you need to subtract 15 to isolate "x".

Madisyn is planting crops in a triangular garden. The triangular garden can be
seen below. What is the amount of fencing that Madisyn needs?
Answer:
The amount of fencing Madisyn needs is approximately 20.77 m
Step-by-step explanation:
The coordinates of the vertices of the triangular garden are;
A(0, 6), B(6, 5), and C(5, -1)
The length of the sides of the triangle can be found through the given coordinates and the distance between coordinates formula presented as follows;
[tex]Distance \ between \ points \ given \ the \ coordinates = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Therefore, the length of AB is [tex]\sqrt{\left (5-6 \right )^{2}+\left (6-0 \right )^{2}} = \sqrt{37}[/tex]
The length of BC is [tex]\sqrt{\left (5-(-1) \right )^{2}+\left (6-5 \right )^{2}} = \sqrt{37}[/tex]
The length of AC is [tex]\sqrt{\left (6-(-1) \right )^{2}+\left (0-5 \right )^{2}} = \sqrt{74}[/tex]
Therefore;
The amount of fencing Madisyn needs = The length of the sides of the triangular garden
The length of the sides of the triangular garden = The length of AB + The length of BC + The length of AC
The length of the sides of the triangular garden = √37 + √37 + √74 ≈ 20.77 m.
The amount of fencing Madisyn needs ≈ 20.77 m.
