x² – 3x + 5x – 15
= x(x-3) + 5(x-3)
= (x+5)(x-3)

Can anyone please help me on my corrections please!

A) the length on the top is 2ft. You were supposed to subtract 11ft from 9ft. The length on the bottom is 17. You get that by adding 5ft and 12ft
b) then you add up all the lengths together.
2+5+12+11+9+17= 56ft

-8x-2y=6 in slope form

Harrizon [31]

Perhaps you mean "slope-intercept" form. Solve for y and reduce the fractions.
.. -8x -6 = 2y . . . . . . . . add 2y-6
.. y = -4x -3 . . . . . . . . . divide by 2

Your line in slope-intercept form is
.. y = -4x -3

Answer:9/4

Step-by-step explanation:

99/8*2/11=9/4*1/1=9/4

Answer: 0.548

Step-by-step explanation:

First you need to remember the formula for PEMDAS(Parenthesis,exponents,multiplication,divison,addition,subtractio)

you can do either multiplication or divison whichever comes first, same with addition+subtraction.

the underlined means to simplify

1.-0.57x3/5+4/7x-1/5+2/5x-4/5

2.-1.71/5+4/7x-1/5+2/5x-4/5

3.-0.342+4/7x-1/5+2/5x-4/5

4.-0.342+0.57x-1/5+2/5x-4/5

5.-0.342+0.57x-0.2+2/5x-4/5

6.-0.342+0.114+2/5x-4/5

7.-0.342+0.114+0.4x-4/5

8.-0.342+0.114+-1.6/5

9.-0.342+0.114+-0.32

10.-0.228+-0.32=-0.548

i did this all in one go so......
