Answer:
The length of a rectangle is 7 inches longer than it is wide. If the area is 170 square inches, what are the dimensions of the rectangle?
Answer by Cromlix(4381) (Show Source): You can put this solution on YOUR website!
x = width x + 7 = length
x(x+7) = 170
x^2 + 7x - 170 = 0
(x + 17)( x - 10)
Therefore x = 10 as x = -17 no answer.
Width = 10 inches
Length = 17 inches
Answer:
A. (0, 6) and (−2, 0)
Step-by-step explanation:
The given equations are:

and

We equate the two equations to find their point of intersection;

We equate everything to zero to get;



When x=0, y=3(0)+6=6
One solution is;
(0,6)
When x=-2,
y=3(-2)+6=0
Another solution is;
(-2,0)
Answer:
.
Step-by-step explanation:
If a graph touches the x-axis at x=c, then (x-c) is a factor of function.
From the given graph it is clear that the graph of function intersect x-axis at x=1 and touch the x-axis at x=-2.
It means (x-1) and (x+2) are not factors of given function but power of (x+2) must be 2.
So, the required function is
...(1)
where, a is a constant.
From the given figure it is clear that the graph passes through the point (-4,-7). So, substitute x=-4 and f(x)=-7 in the above function.
Substitute
in (1).
Therefore, the required function is
.
Answer:
28
Step-by-step explanation:
42 ÷ 1 × 1/2
= 28
Answer:
x^2 + x^5 + C.
Step-by-step explanation:
∫2x + 5x^4 dx
= 2 * x^2/2 + 5 * x^5/5 + C
= x^2 + x^5 + C.
