(y-3)(y+10) find the product please​
allochka39001 [22]

Answer:

y^2 +7y-30

Step-by-step explanation:

Step 1:  Use FOIL

y·y = y^2

y· 10= 10y

-3·y= -3y

-3·10= -30

Step 2: <em>combine like terms</em>

y^2+ 10y-3y-30

7^2+ 7y-30

and thats all :)

hope this helped

Consider the graph with four lines below. On a coordinate plane, line a has a positive slope and goes through points (negative 1
yan [13]

Answer:

The correct option is;

line a and line b

Step-by-step explanation:

Lina a passes through (-1, 0) and (1, 2)

Line b passes through (2, 2) and (-1, -1)

Line c passes through (0, 3) and (1, 0)

Line d passes through y = 1

An equation that has no solution

By examination, from the plot of the coordinates using an online tool, the system that would have no solution is the system of line a and line b because they are parallel lines and cannot meet or have a point where there is a common solution, therefore, there are no solutions when the equations of the two lines are combined in one equation

Slope of line a = -2/-2 = 1

Slope of line b = 3/3 = 1

The slopes of lines a and b are equal, therefore, line a and line b are parallel.

The length of the rectangle is 1/4th the width of the rectangle. The perimeter is 35 ft. How long is the length and width?
Monica [59]
---- x ----
|            | 0.25x
---- x ----


x + x + 0.25x + 0.25x = 35
2.5x = 35
x = 35/2.5
x = 14
width is 14

length is 1/4 this.
length = 7/2
