Answer:
a) 18
b)x^2+10x+18
c)x^2 -6x+2
Step-by-step explanation:
This is a case of plugging in the value into f(x).
a) f(-8)= -8^2 + 6(-8) +2
f(-8)= 64 + (-48) +2
f(-8)=64 + (-46)
f(-8)=18
b) f(x+2)= (x+2)^2+6(x+2)+2
So here I'll take a break to explain what's going on, because x+2 is a binomial meaning two terms and it is being squared I have to multiply the whole thing by itself. Meaning: (x+2) x (x+2), this is also known as foiling!! and for the next part its distributing 6 into x and 2.
f(x+2)= x^2+4x+4+6x+12+2
I'll reorder it
f(x+2)= x^2+4x+6x+12+2+4
f(x+2)= x^2+10x+18
c) f(-x)= -x^2+6(-x) +2
f(-x)= x^2 -6x+2

A sailboat took 1/3 of an hour to travel
10 miles. At the same pace, how many
hours would the sailboat take to travel
120 miles?
Answer:
4 hours

Step-by-step explanation:
*Not sure how your teacher wants you to round this, but here is how I do it
All you need to do to find the decimal form of a fraction is to take the numerator and divide it by the denominator :
2 / 3 = 0.6666666.... and keeps going
= 0.67
To convert this decimal to percentage just multiply it by 100 :
0.67 x 100 = 67 %

Step-by-step explanation:
If L and M are parallel then the angles will add up to 180 (a straight line), so:
6x+8+4x+2=180
10x+10=180
10x=170
x=17

If AB= x+4, BC=2x-10, and AC=2x+1, then find the value for x
Answer:
[tex] \boxed{x = 7} [/tex]
Step-by-step explanation:
Given:
AB = x + 4BC = 2x – 10AC = 2x + 1We can illustrate this relationship as:
(2x + 1)
___↑___
| |
A — B — C
|____|___|
↓ ↓
(x + 4) (2x – 10)
_______________________________
When you are given an algebraic expression for the length of a segment, you can solve for that value by knowing that the sum of two segments AB + BC = AC.
Thus:
(x + 4) + (2x – 10) = (2x + 1)
[Regroup terms]
(x + 2x) + (4 – 10) = (2x + 1)
[Simplify]
(3x – 6) = (2x + 1)
[subtract 2x from both sides to isolate the variable]
(3x – 6) – 2x = (2x + 1) – 2x
[Regroup terms]
(3x – 2x) – 6 = (2x – 2x) + 1
x – 6 = 1
[Add 6 to both sides to isolate the constant]
x – 6 + 6 = 1 + 6
[Simplify]
x = 7

Answer:
multiply 8x4
Step-by-step explanation:
Answer:
36 tiles
Step-by-step explanation:
Since there is 1 extra tile on each side of the 8x8 pool, we can say that the entire area of the picture is 10x10.
Subtracting 8x8 from 10x10 we get
(10x10) - (8x8) = ?
100 - 64 = 36
36 tiles are around the 8x8 pool

4. Order the sides of each triangle from shortest to longest.
X
85°
41°
54°
W
V
1. Longest
a.
VW
2. Middle
b. WX
3. Shortest
XV
c.
Answer:
XV < XW < WV
Step-by-step explanation:
The side lengths are proportional to angles they see
The side that sees the largest angle has longest measurement and the one that sees smallest angle would be shortest therefore we can order sides from shortest to longest like this :
XV < XW < WV
