The equation for area of a triangle is A= 1/2bh so a=1/2(12cm)(9.6cm)
You would subitute -2 for x in the equation
f(-2)=x^2-6
PEMDAS so exonents
-2^2-6
negative times a negative= positive
4-6
f(-2)=-2
f(x) means that you subsitute x for x in the equation exg
f(1)=x+2 means f(1)=1+2
f(4)=x+2 means f(4)=4+2
Answer:
False.
Step-by-step explanation:
1. 0.2 is 1 percent of 20.
2. 0.2x20 is 4
3. 14 divided by 0.2 is 70, that means 14 is 70% of 20.
4. Therefore, 4 is 20% of twenty.
X=7 because 7 squared equals 49
