1: 47
2: 19
3: 7
4: 11
5: 31
Step-by-step explanation:
input the number next to F where x is. example: f(-2)= 8(-2)^2-4(-2)+7 and then solve using PEMDAS giving f(-2)=47 and so on.
Answer:
i would reword this to 6x+7=61
Step-by-step explanation:
So.
move the 7 to the right side of the equation but as an opposite number so in this case its gonna be a negative
61-7=54
then you divide the number and get your missing numbers
54/6=9
d=9
plug it in
6(9)+7=61
6 is in the hundredths place (1/100) in 4.768... so 6 has the value of 0.06
X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7
We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25
answer: the number would be: -25.
Answer:
The value of 
Step-by-step explanation:
Let's recall the the formula for volume of a pyramid.
Volume of a Pyramid 
....equation 
where 
and 
Now we have been given the values of 
and 
and have to find the value of 
Plugging the values of and in equation
Now we can also check our previous results.
So, our final answer is
