Step-by-step explanation:
multiply all the numbers by 4 I think except for the exponent
Since the area of a square is side squared, you can find the length of each side by finding the square root of the area, which is 5. Since there are four sides in a circle, just multiple 5 by 4 and your answer is 20 units.
Answer:
36
Step-by-step explanation:
(7+
)(7- )
this is in the form of a^2-b^2 formula
a^2-d^2=(a-b)(a+b).so write,
(7)^2-( )^2
=49-13
=36
Answer:
409968000
Step-by-step explanation:
13 rounded years is equal to 409968000 seconds
So in distributive property you multiply the outside number by the two inside so in this case 2(a) + 2(-2) = 3(a) + 3(-5)
Which will give you
2a+ - 4 = 3a + - 15
Or
2a-4=3a-15
Then if your solving for a your can subtract 3a from 2a giving you
- a-4=-15
Then add 4 to - 15
-a =-11
Then divide by negative 1 (this is so a isn't negative)
A=11
Hope this helps!
