Answer:
45 to 18 it's easy
Step-by-step explanation:
subtract 18 from 63 and there is your ratio
8^2 + b^2 = 24^2
64 + b^2 = 576
-64 -64
b^2 = 512
Take the square root from b^2 and 512 =
b = 22.627
Answer 22.63 (rounded up)
We are to write the expression for:
<span>The product of two and The sum of a number and eight
</span>
This means 2 is to be multiplied with the sum of 8 and the number. The number is n. So sum of 8 and number is 8 + n
Product of 2 and the sum is 2 (8 + n)
Therefore, the correct answer is option D
1) x=100
2) m=1000
3) v=49
4) v=64
5)n=81
6) x=22
7) b=1
8) b=-8
Hi there
-(-2a+13)+(-9-2)-(-7a-3)
-(-2a+13)-9a-2-(-7a-3)
Distribute the negative sign
-(-2a+13)-9a-2+-1(-7a-3)
-(-2a+13)+-9a+-2+-1(-7a)+(-1)(-3)
-(-2a+13)+-9a+-2+7a+3
Distribute
2a+-13+-9a+-2+7a+3
Combine like terms
2a+-13+-9a+-2+7a+3
(2a+-9a+7a)+(-13+-2+3)
=-12
Any questions ?
I hope that's help !
