3 × (c2 − 8) for c = 3
Answer:
I am assuming c2, is c^2.
3 × (c2 − 8)
=3 ×(3^2-8)
=27-8
=19
If c2 is c*2
Then,
3 × (c2 − 8)
=3×(6-8)
=18-24
=(-6)

6√3
Step-by-step explanation:
6 is x. side across from right angle (12) is 2x. so 6x2 to get 12. missing side is x√3. so 6√3
Answer:
6√3
Step-by-step explanation:
using the pythagorean theorem you can plug in the numbers to get √(12^2 - 6^2) = √(144-36) = √108 = 6√3.
Is Figure A congruent to Figure B? Explain.
No, because the orientation of Figure B is not the same as Figure A.
Yes, because Figure B can be obtained from Figure A by a series of translations.
Yes, because Figure B can be obtained from Figure A by a rotation and a translation.
No, because there is no sequence of translations, rotations, and reflections by which Figure B can be obtained from Figure A.

A: 48
B: 3
C: 4,800
Answer:
48
Step-by-step explanation:
40% of 120
40 x 120 = 4800 / 100 = 48
100
Answer:
A- 48
Step-by-step explanation:
You divide your percentage by 100. So, 40% would be 40 divided by 100 or . 40. Once you have the decimal version of your percentage, simply multiply it by the given number.

3y=4.8 (I'm so confused it isn't even funny)
Answer:
y = 1.6
Step-by-step explanation:
4.8/3=1.6
3*1.6=4.8
Answer:
[tex]y = 1.6[/tex]
Step-by-step explanation:
[tex]3y = 4.8[/tex]
Use inverse operations to solve this problem. Inverse operations is a method of solving a linear (and in some cases quadratic) equation. This method has one do the same operations to both sides such that it cancels out the operations done to the variable, and hence, it leaves one with the solution.
In this case, all one has to do is divide both sides by the coefficient of the varibale (y).
[tex]3y = 4.8[/tex]
÷[tex]3[/tex]
[tex]y = 1.6[/tex]
In what case does 8 + 8 = 4?

You ride your bicycle along the outer edge of the park. Then you take a shortcut back to where you started. Find the length of the shortcut. Round your answer to the nearest tenth.
Answers:
100m
60m
116.6m
160m
Answer:
116.6
Step-by-step explanation:
Answer:
116.6
Step-by-step explanation:
To solve this equation you would need to use the pythagorean theorem. The pythagorean theorem is [tex]a^{2} +b^{2}= c^{2}[/tex] where a and b are lengths of the triangle and c is the hypotenuse (the longest side of a triangle) in this case, the short cut.
First, you would substitute values into the equation:
[tex]100^{2}+60^{2}= c^{2}[/tex]
Then, you would multiply out the squares:
[tex]10,000+3600=c^2[/tex]
Add the numbers together:
[tex]13600=c^2[/tex]
Take the square root of both sides to get the answer:
[tex]c=116.619037897[/tex]
Then round to the nearest tenth to get the answer: c=116.6
negitive 17plus n over 5 =33 what is n
Answer:
250
Step-by-step explanation:
-17+n/5=33
n/5=33-(-17)
n/5=33+17
n/5=50
n=50*5
n=250
n=182
Step by Step Explanation:
The equation we would start out with is:
[tex] \frac{ - 17 + n}{5} = 33[/tex]
From here, we need to multiply both sides by 5. This would create an equation of -17+n=165, as we canceled out the 5.
Then, you need to add 17 to both sides to isolate the variable. This would make the equation n=182, our final answer.
The graph of y = f(x) is shown.
a) Find f(0)
4-
3.
b) Give the roots of f(x) = 0
Answer:
f(0) = 2
Roots are;
-2 and -1
Step-by-step explanation:
F(0) simply refers to the y-values when x = 0
This is the point at which the graph crosses the y-axis
the value here is 2
To
find the roots of f(x) , we simply find the points at which the plot crosses the x-axis
we have this at x = -2 and x = -1
These are what represents the roots of the equation

y = -4x + 1
11y = x + 146
Step 2: Solve for x
Substitution
Substitute in y: 11(-4x + 1) = x + 146Distribute 11: -44x + 11 = x + 146[Addition Property of Equality] Add 44x on both sides: 11 = 45x + 146[Subtraction Property of Equality] Subtract 146 on both sides: -135 = 45x[Division Property of Equality] Divide 45 on both sides: -3 = xRewrite/Rearrange: x = -3Step 3: Solve for y
Define original equation: y = -4x + 1Substitute in x: y = -4(-3) + 1Multiply: y = 12 + 1Add: y = 13a supermarket has 129 crates of apples each crate holds 125 how many apples does the supermarket have
6. Mary flips the coin and then she spins the spinner. What is the
probability that the coin will not land on tails, and the spinner will not land
on 3? Spinner (1, 2, 3, 4); Coin (H, T) *
A 1/8
B 1/4
C 3/8
D 1/2
Answer: For the coin, there are 2 possibilities which are Heads and Tails so the possibility is 1/2 and for the spinner it will be 1/4 because there are 4 possibilities.
