Answer:
36
Step-by-step explanation:
11*11=4
(1+1)*(1+1)=4
2 * 2 = 4
22*22=16
(2+2)*(2+2)=16
4 * 4 = 16
33*33=?
(3+3)*(3+3)=?
6 * 6 = 36
So the answer is 36
Series: 4, 16, 36
Answer: I think it’s y = mx+b?
Step-by-step explanation: well if you really need it-
Where:
m is the slope, and
b is the y-intercept
First, let's find what m is, the slope of the line...
The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.
Answer:
100
Step-by-step explanation:
f(n+1)=-10 f(n)
f(1)=1
put n=1
f(2)=-10f(1)=-10×1=-10
put n=2
f(3)=-10f(2)=-10×-10=100
Answer:
C. x = 3cm
Step-by-step explanation:
The formula for volume of a triangular prism is
<u>V = base * height</u>
x in this case equals height, and the base is the area of the triangular base, which is
<u>A(triangle) = 1/2 b*h</u>
= 1/2 7*10 = 35 square centimeters
Plug this back into our formula:
V = base * height
105 = 35x
Solve for x.
105/35 = x
<u>C. x = 3 cm</u>
<u>Answer:</u>
Two times the difference of a number x and 7 plus 10.
<u>Step-by-step explanation:</u>
We are to write a phrase which matches the following algebraic expression below:

We can see that there is a bracket with a coefficient outside it so we can express it as:
<em>'Two times the difference of a number x and 7'.</em>
While + 10 can be added to it to complete the phrase:
Two times the difference of a number x and 7 plus 10.
