Answer: Variant C
Step-by-step explanation:
f(x) = 3x^2 − 4
For finding f(-2) just replace x with - 2 like this:
f(-2)=3*((-2))^2-4=3*4-4=12-4=8
1,000/40= 25 calculators
1,000/40.30=24.8
she can only buy 24 calculators all together
You use distributive property. So (5 x 2)-(5 x x)= 10 - 5x.
The smaller the length u can figure out and if u can't put a small square in the cornorn
