Answer:
The answer is D: x (Squared) + 4x - 21.
Step-by-step explanation:
(X-3)(x+7)
First you multiply the first x by x, to get x squared. Then you multiply the first x by 7 to get 7x.
Next you multiply the -3 by the second x, to get -3x. Then you multiply the -3 by the 7 to get -21.
Written in order it would look like:
X (squared) + 7x -3x -21
You can combine the 7x and the -3x because they are like terms. This would leave you with:
x (squared) + 4x - 21
Answer:
1402.5 Cubic Units
Step-by-step explanation:
Volume of a Triangular Prism: V = 
b - base
h - height
l - length
15 is the height, 17 is the length, and 11 is the width (assuming which is the base).

The volume of the prism should be 1402.5 cubic units.
Slope is -1/2. The y value decreases one every 2 increases in the x value. The y-intercept is y = 2. The equation is Y = -1/2x + 2

The farmers were happy because the botanist (plant scientist) said their grape and wheat fields would have plentiful yields this coming harvest.
Answer:
<em>$40 </em>will be the total cost of the ribbon.
Step-by-step explanation:
To find the cost of ribbon to be put on the edges of rectangular banner, we need to:
1. Find the perimeter of the rectangle.
2. Multiply the perimeter with the per foot cost to find the total cost.
Let us find the perimeter first:
Perimeter of a rectangle is given as:

Here, the dimensions of rectangle are 4ft by 6ft.
So, perimeter = 
It is given that per foot cost is $2.
Total cost of the ribbon = 
<em>$40 </em>will be the total cost of the ribbon.
