Answer:
35
Step-by-step explanation:
3 + 2 = 5
7 times 5 = 35
Answer:
100
Step-by-step explanation:
Since the second 4 is two decimal points away from the first 4, the answer should be 100 (two zeros)
It depends which type of object are you talking about? Or a place?
We have the expressions:
![f(x)=x^2+6x+15](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%2B6x%2B15)
![y=x^2-4x+9](https://tex.z-dn.net/?f=y%3Dx%5E2-4x%2B9)
![f(x)=x^2-8x](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2-8x)
![y=x^2+7x-2](https://tex.z-dn.net/?f=y%3Dx%5E2%2B7x-2)
Now, with this we operate as follows:
a)
![f(x)=x^2+6x+15=x^2+6x+9+15-9](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2%2B6x%2B15%3Dx%5E2%2B6x%2B9%2B15-9)
![\Rightarrow(x+3)^2+6](https://tex.z-dn.net/?f=%5CRightarrow%28x%2B3%29%5E2%2B6)
Then, the axis is x = -3 and the vertex (-3, 6)
b)
![y=x^2-4x+9=x^2-4x+4+9-4](https://tex.z-dn.net/?f=y%3Dx%5E2-4x%2B9%3Dx%5E2-4x%2B4%2B9-4)
![\Rightarrow(x-2)^2+5](https://tex.z-dn.net/?f=%5CRightarrow%28x-2%29%5E2%2B5)
Then, the vertex is (2, 5) and the axis is x = 2.
c)
![f(x)=x^2-8x+4-4\Rightarrow(x-2)^2-4](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E2-8x%2B4-4%5CRightarrow%28x-2%29%5E2-4)
Then, the vertex is (2, -4) andd the axis is x = 2.
d)
![y=x^2+7x-2=x^2+7x+\frac{49}{4}-2-\frac{49}{4}](https://tex.z-dn.net/?f=y%3Dx%5E2%2B7x-2%3Dx%5E2%2B7x%2B%5Cfrac%7B49%7D%7B4%7D-2-%5Cfrac%7B49%7D%7B4%7D)
![\Rightarrow(x+\frac{7}{2})^2-\frac{57}{4}](https://tex.z-dn.net/?f=%5CRightarrow%28x%2B%5Cfrac%7B7%7D%7B2%7D%29%5E2-%5Cfrac%7B57%7D%7B4%7D)
Then, the vertex is (-7/2, -57/4) and the axis is -7/2.
You multiply them together so it is 360 it will sometimes also look like this
8(45+7) and with that you would then just multiply the 8 to the 45 and the 7
