Remember
x-(-y) means x+y since minusing a negative cancels

-3z^7+5z^7
addthe coeficients
one way to show is undistribute
-3z^7+5z^7=(z^7)(-3+5)=(z^7)(2)=2z^7

answer is 2z^7

Explain how to use a coordinate plane to find the area of a rectangle with vertices (–4, 9), (–4, –3), (–1, –3), and (–1, 9). wh
liberstina [14]

the formula for area of a rectangle is

Area = length x width

since both the length and the width of the rectangle lie on the same x and y axis, we can find the distance between the width and the distance between the length by subtracting

(-4,9) (-4,-3)

these points lie on the same x axis, so they create a vertical line

9-(-3) = 12

12 units is the distance between them

(-4,-3) (-1,-3)

these points lie on the same y axis, so they create a horizontal line

-1-(-4) = 3

3 units is the distance between them

now that we have the length and the width, we can find the area

A = 12 x 3

A = 36 units²

The length of a rectangle is (x+3) inches long,and the width is 3⅖ inches.If the area is 15 3/10 square inches,write an equation
tino4ka555 [31]

Answer:

(x + 3) = 9/2

Step-by-step explanation:

Here, we want to write an equation to find the length of the rectangle

Mathematically;

Area of rectangle = length * breadth

15 3/10 = (x + 3) * 3 2/5

(x + 3) = 15 3/10 divided by 3 2/5

(x + 3) = 153/10 * 5/17

(x + 3) = 9/2

$5,000 is invested at 3% interest. How much money must be invested at 5% interest so that the total interest from the two invest
Nataly [62]
3% interest on 5,000 = 150

275 (the total amount wanted) - 150 (from initial investment)= 125

x (5%) =125
x (0.05)= 125
x/0.05)= 125/0.05
x=2500

you need to invest 2500 at 5% to get the additional 125

125 plus 150= 275
