Answer:
12 + 2x
Step-by-step explanation:
2(10) + 2(x - 4)
20 + 2(x - 4)
20 + 2x - 8
12 + 2x
Answer:
-6
Step-by-step explanation:
2(10)+2(x-4)=0
20+2x-8=0
20-8+2x=0
12+2x=0
2x=-12
x=-6
2x + 8 = 14 solve the equation you may find using algebra tiles to be helpful
Answer:
x = 3
Step-by-step explanation:
2x + 8 = 14

What Are The Questions
A rectangular garden has a walkway around it. The area of the garden is 6(5.5x + 2.5). The
combined area of the garden and the walkway is 7.5(8x +4). Find the area of the walkway around
the garden as the sum of two terms.
Answer:The area of the walkway around is 26 x + 16 as the sum of two terms
Step-by-step explanation:
A rectangular garden has a walkway around it
1. The area of the garden is 4(4.5 x + 1.5)
2. The combined area of the garden and the walkway is 5.5(8 x + 4)
We need to find the area of the the walkway
To find the area of the walkway by subtracting the area of the
rectangle from the combined area
∵ The combined area = 5.5(8 x + 4) ⇒ simplify it
∴ The combined area = 5.5(8 x) + 5.5(4)
∴ The combined area = 44 x + 22
∵ The area of the garden = 4(4.5 x + 1.5) ⇒ simplify it
∴ The area of the garden = 4(4.5 x) + 4(1.5)
∴ The area of the garden = 18 x + 6
Now subtract the area of the garden from the combined area
∵ Area of the walkway = (44 x + 22) - (18 x + 6)
∴ Area of the walkway = 44x + 22 - 18 x - 6
- Add like terms
∴ Area of the walkway = (44 x - 18 x) + (22 - 6)
∴ Area of the walkway = 26 x + 16
The area of the walkway around is 26 x + 16 as the sum of two terms

How do I complete the square for 4x^2+ 8x-5= 0?
Answer:
man I have no idea dude I don't really know squares if you're talking about square root I really don't know
Answer:
x = [tex]\frac{1}{2}[/tex], - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
This is not so fun!
[tex]4x^{2} + 8x - 5 = 0\\[/tex]
Step 1: Move the 5 to the right side
[tex]4x^{2} +8x = 5[/tex]
Step 2: Divide thru by 4
[tex]x^{2} + 2x = \frac{5}{4}[/tex]
Step 3: Divide 2 (from 2x) by 2 and square the result and add that to both sides of the equation.
2/2 = 1 1 squared = 1
[tex]x^{2} + 2x + 1 = \frac{5}{4} +1 = \frac{9}{4}[/tex]
Step 4: Factor the left side
[tex](x + 1)^{2} = \frac{9}{4}[/tex]
Step 5: Take the square root of both sides
x + 1 = ±[tex]\sqrt{\frac{9}{4} }[/tex] = ± [tex]\frac{3}{2}[/tex]
Step 6: Move the 1 to the right side and add the results
x = -1 ± [tex]\frac{3}{2}[/tex] = -1 + [tex]\frac{3}{2}[/tex] or -1 - [tex]\frac{3}{2}[/tex]
= [tex]\frac{1}{2}[/tex] or - [tex]\frac{5}{2}[/tex]
And bingo, you have the solutions by completing the square. Lot of fun, huh.
Is that right?
Please help
Answer:
yes x = 16
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, that is
133 = x + 117 ( subtract 117 from both sides )
16 = x

Answer:
1 = 3x = 3 x 356 = 1068
2 = 5x = 5 x 356 = 1780
Step-by-step explanation:
Rupees = 2848
3x + 5x = 2848
8x = 2848
x = 2848 / 8 = 356
1 = 3x = 3 x 356 = 1068
2 = 5x = 5 x 356 = 1780

A teacher lives 8 miles from school. She drives a 2015 Chevy Camaro that gets 19 miles per gallon of gas. How much fuel will she need to get TO AND FROM work for the week?
Answer:
Step-by-step explanation:
Technically we cannot solve this without knowing how many days a week that she works.
f=(16mi*d)(gal/19mi)
f=(16/19)d
We would have to assume that she works a certain amount of days. If we assume she works every day
f=7(16/19)=112/19, approximately 5.9 gal
