Hello! our answer here is going to be:
43.
Lets understand this a little better!
when dealing with exponents, it is the base number (3) times its self how ever many the above number is (3 again)
so, it wont be 3 x 3, but instead 3 x 3 x 3 because that's how much the exponent is.
same rule applies with 4^2!
Answer:
2x^2
Step-by-step explanation:
if you draw a diagonal, you will have two triangles with base x and height x
so area= 2 * 1/2 * b * h = b * h= 2x * x
The next pattern is 364...
the pattern is by multiples of 3 added to the preceding number;
example, 1+3= 4 that's 3
4+9=13 because 3*3 is 9
13+27=40 coz 9*3 is 27
40+81=121 coz 27*3 is 81
121+243=364 coz 81*3 is 243
and so on and so forth..
hope this helps!

this is the right answer ^
This is a problem of
fact families, but <em>what is fact families?</em> Well it is a family of four things. Two of them are additions and two of them are subtractions. So this question asks about fact families by w<span>riting the <em>subtraction fact two ways</em>. So we have:
</span><span>
First way. So let's take the number 10 and explain this problem using triangles. Let's say that we have 10 triangles in the beginning:
</span>Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ
So I want to take away 3 triangles, then by taking away 3<em> what is left? </em>Well the answer is 7:
Δ Δ Δ Δ Δ
Δ Δ
That is, if we subtract 3 from 10 then the result is:
Second way. In this subtraction we take the same 10 triangles:
Δ Δ Δ Δ Δ
Δ Δ Δ Δ Δ
Now I want to take away 7 triangles, then by taking away 7 what is left is 3:
Δ Δ Δ
That is, if we subtract 7 from 10 then the result is:
