If ab = 20 cm and bc = 4 cm, then what are the possible lengths for ac so that ab, bc and ac can form a triangle?

1 answer:

3 0

16<ac<24
If it is less than 16 it will not form a triangle and if it is more than 24 the other two legs will not be larger than ac is.

4×11+1=45

A+B+C=180 60+75+C=180 180_130=c c=45

Answer:

f(-3) = -3

Step-by-step explanation:

Step 1: f(x) means "f of x" and f(-3) means "f of -3", so you have to replace all the "x" letters in the function with the value -3.

$f(x)=x^4+3x^3-x^2+6\\f(-3)=(-3)^4+3(-3)^3-(-3)^2+6$

Step 2: Apply the exponents. <em>Make sure you remember to put in the -3 and not just 3.</em>

$f(-3)=81+3(-27)-9+6$

Step 3: Use BEDMAS rules to complete the calculation.

$f(-3)=81-81-9+6$

$f(-3)=-3$

Therefore the answer is f(-3) = -3.
