Answer:
560x^3y^4.
Step-by-step explanation:
The (r+1)th term of (a + b)^r = nCr a^(n-r) b^r
We want the fifth term so r = 5 - 1 = 4:
(4 + 1)th term = 7C4 x^(7-4) (-2y)^4
= 35x^3 16y^4
= 560x^3y^4.
-4x^2-5(x+3)+x^2 :
-4x^2-5x-15+x^2
-3x^2- 5x -15
Answer:
C 2x^2 + 3/2x -5
Step-by-step explanation:
f(x)=x/2-2
g(x)=2x^2+x-3
(f+g) (x)=x/2-2+2x^2+x-3
Combine like terms
2x^2 + 3/2x -5

Parabolas are graphs that make U-shapes and are formed from quadratic equations.
Vertical Parabolas
There are 2 different types of parabolas: vertical and horizontal.
- Vertical parabolas have a vertical axis of symmetry. So, they open up or down.
- Horizontal parabolas have a horizontal axis of symmetry. So, they open left or right.
If the x-value is squared, then the parabola is vertical. So, this graph must open up or down.
Positive A-Value
The a-value is the coefficient before the squared term. In a vertical parabola, the graph opens up if the a-value is positive. On the other hand, the graph opens down when the a-value is negative.
In this case, the graph is a vertical parabola that opens up. This means that the range will have a minimum value but no maximum.
The answer for the question shown above is: <span>The square footage of a house that is 1200 square feet is the "</span>Area".
The explanation is shown above:
1- By definition, the area is the measure of a two-dimensional surface.Its units can be written in m^2, ft^2, in^2...However, in the International System of Units is m^2.
2. This is very useful when you want to know the surface of a house. If it is a rectangular house, you can calculate the area as below:
A=LxW
Where L is the length and W is the width
