Answer:
Step-by-step explanation:
4/5 of 3 is the answermultiply and divide by fractions is the topic
Answer:
We will add 64 to both sides.
x=8±√20
Step-by-step explanation:
Here we are given the equation:
![x^{2}+16x=-44](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B16x%3D-44)
Now we take half of the coefficient of x and add it to x.
Coefficient of x is 16, half of 16 is 8.
Also we add square of 8 to both sides.
So new equation becomes:
![x^{2}+16x+64=-44+64](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B16x%2B64%3D-44%2B64)
Completing the square:
![(x+8)^{2}=20](https://tex.z-dn.net/?f=%28x%2B8%29%5E%7B2%7D%3D20)
NOw let us simplify it to get the value of x.
Taking square root on both sides:
![x+8=+/-\sqrt{20}](https://tex.z-dn.net/?f=x%2B8%3D%2B%2F-%5Csqrt%7B20%7D)
Bringing 8 to the right side:
x=8±√20
Answer:
The first one is arithmetic and the second one is geometric.
Step-by-step explanation:
Arithmetic is basically like skip counting. 1 time 7 is 7, two times 7 is 14, etc...
Geometric is anything all the numbers added to get a total of 360. The next two terms for the first one is 42 and 49.
Answer:
anything higher higher than 8
Step-by-step explanation:
if X is 1, the other number is 9 (9-1=8)
if X is 10'000, the other number would be 10'008 and so on
