Answer:
7x + 33 -I could be wrong I'm not an expert in maths jus trying to help
Step-by-step explanation:
x + 13 9x-7
so first you need to times both by two because there are two of both sums
2(x+13) so you times both numbers by 2 so
= 2x+26
and do the same with 9x - 7 so
2(9x-7) = 18x - 14
and then you add them together and find the like terms.
Like terms means for example in the equation:
2x + 3x - 4 + 3
the like terms are the two numbers that are the same like 2x and 3x are the same since they are both the same term and since there is a plus sign before the 3x you add them so 5x and then you need to do -4 + 3 = 7 and so the answer is 5x + 7.
In this case its:
2x + 26 + 5x + 7. So the like terms are 2x and +5x and +26 and +7.
So 2x + 5x = 7x and 26 + 7 = 33.
So the final equation is 7x + 33
Hope this helps :D
Answer:
The working is done in the image attached.
Anyways the ratio of the independence is the five points he was the ratio amount of
For this equation, there is no solution.
Alrighty
3 cubes
if you stack them then you can cover, at most 3 faces
each cube has 6 faces
so 6*3=18
minus the 3 coverd is 18-3=15
so if the surfece area is equal to 15 of those faces ten
84=15 faces
divide by 15
84/15=area of 1 face
a cube has 6 faces to multiply by 6
84/15 times 6=504/15=168/5=33.6 square inches is the surface area of one of grogg's cubes
