Answer:
a)(x+h+2)²=x²+2xh+h²+4x+4h+2
b)(x+h+2)²–(x+2)²=2xh+h²+4h
c)2x+4+h
Step-by-step explanation:
f(x)=x²+4x+2
Aight so for part a you have to replace x with x+h
a)f(x+h)=(x+h)²+4(x+h)+2=x²+2xh+h²+4x+4h+2
and then for part b you need to subtract f(x) from part a:
b)f(x+h)–f(x)=x²+2xh+h²+4x+4h+2–x²–4x–2===>
2xh+h²+4h
and for part c divide the answer by h:
c)
and if you limit h by 0 you'll get the derivative of f(x)
This is a multiplication problem.You need to regroup when you multiply.When you multiply you should know your place value so the problem can be lined up.If you were to do this the answer would be 168
Answer:
The answer to your question is 16 in²
Step-by-step explanation:
Data
Square Triangle
Length of a side 2 in
Base 2 in
Height 3 in
Process
1.- Calculate the area of the square
Area = side x side
-Substitution
Area = 2 x 2
-Result
Area = 4 in²
2.- Calculate the area of the triangle
Area = base x height / 2
-Substitution
Area = 2 x 3/2
-Result
Area = 3 in²
-Multiply the area by four (number of stars)
Area = 4 x 3 = 12 in²
3.- Calculate the area of the star
Area = Area of the square + area of the triangle
-Substitution
Area = 4 + 12 = 16 in²
Answer:
A 4,320
Step-by-step explanation:
6*2=12
