➷ Just substitute the given value into anywhere you see the term x:
2 x 4^2 + 12
Follow the PEMDAS rule:
(calculate the exponential first)
4^2 = 16
Now we have:
2 x 16 + 12
(now the multiplication needs to be calculated)
16 x 2 = 32
Now we have:
32 + 12
Add them together to get the answer:
44 <== this is the answer

Answer:
10.626
Step-by-step explanation:
There's multiple ways to go about it. See how
5.06 * 2.1 = (5 + 0.06)(2 + 0.1) = 5*2 + 0.06*2 + 5*0.1 + 0.06*0.1 =
= 10 + 0.12 + 0.5 + 0.006 = 10.626
Please notice how breaking up the product into smaller parts has let us make all the computations without too much hassle.
Answer:
y=7x+5
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=7(x-(-2))
y+9=7(x+2)
y+9=7x+14
y=7x+14-9
y=7x+5

9units sorry for not showing work though but glad I can help
The answer is 12.
Steps
If that number is x
(3+x)/(8+x)=3/4
"Cross multply"
4(3+x)=3(8+x)
12+4x=24+3x
x=12
To check: add 12 to 3 and 8. 3+12=15 and 8+12=20. 15/20=3/4
