( ) ,(5),(20),(0),(7),(5,7),(5,20,(5,0),(20,0),(20,7),( 0,7) (5,20,0),(5,20,7),(20,0,7), , (5,0,7) , (5 ,20,0 ,7)
A
The only one you can eliminate on sight is C. You are going to get an x^3 somewhere along the line.
You can eliminate D on sight as well. The x^3 term is 12x^3 not 7x^3
Doesn't leave much does it?
(3x + 2)(4x^2 - 2x - 7)
3x: 12x^3 - 6x^2 - 21x
2 : 8x^2 - 4x - 14
======================= Add
12x^3 + 2x^2 - 25x - 14
Answer: A
Answer: f(x)=x^2+2x+1 and g(x)=-x^2+1 ==> 1st option
Both are quadratic equations: -x^2 or x^2
Blue graph: x^2 since it's facing up
f(x)=(x-b)^2
Vertex: When x=-1, y=0 ==> 0=(-1+b)^2
0=-1+b
b=1
f(x)=(x+1)^2
f(x)=(x+1)(x+1)
f(x)=x^2+x+x+1
f(x)=x^2+2x+1
Red graph: -x^2 since it's facing down
g(x)=-x^2+b
Vertex: When x=0, y=1 ==> 1=(0)^2+b
1=0+b
g(x)=-x^2+1
f(x)=x^2+2x+1 and g(x)=-x^2+1 ==> 1st option
Given:
The expression is
To find:
The constants in the given expression.
Solution:
Terms can be a number, variable and product of both. these are separated by "+" sign.
Variables terms: These terms contains at least one variable.
Constant terms: These terms are free from the variables. it means there are no variable.
We have,
In this expression, the terms are 6x, -8, 4y, 5, variable terms are 6x, 4y and constant terms are -8, 5.
Therefore, the last option is correct, i.e., -8, 5.
x= 22.5
