Answer:
2x+18
Step-by-step explanation:
We can start by distributing the 2 to each term in the parentheses...
2(x)+2(9)
Multiply
2x+18
Answer:
Step-by-step explanation:
2a+3x+a+5x combine like terms
3a+8x
The answer is option B. In the distributive property you need to multiply the constant that is outside of the parenthesis, with the terms that are inside :)
Answer is 13 because the numbers are increasing though odd numbers that are also increasing if that makes sense.
It’s going from 4 > 9 > 16 > 25 > 36
so from 4-9 it adds 5 and from 9-16 it adds 7 and goes on so that’s it’s like
+5 > +7 > +9 > +11
sorry if it doesn’t make good sense
Answer:

Step-by-step explanation:
The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:

where:
is the area of the base, where
L is the length of the base
is the area of each triangular face, where
h is the height of the face
Substituting,

For the model in this problem,
L = 12
h = 8
Therefore, the surface area here is:
