Answer:
2x² +2x - 12
Step-by-step explanation:
area of rectangle = length X width
length = x+3
width = 2x - 4
Area = (x+3)(2x-4)
= x(2x-4) +3(2x-4)
= 2x² - 4x + 6x - 12
= 2x² +2x - 12
Answer:
prime
Step-by-step explanation:
this equation is not factorable
Answer:
Y intercept (0,2)
X intercept (3, 0)
Step-by-step explanation:
The y intercept is the value when x = 0 (or where it crosses the y axis)
Y intercept (0,2)
The x intercept is when y =0 ( or where it crosses the x axis)
X intercept (3, 0)
8x2=16 and 11x2=22 all you have to do is add 16+22 and that gives you 38 i hope this helped
First solve for x in the first equation. So you'll have to substitute,
5(3x-7)=20
15x-35=20
Then add 35 to both sides.
15x=55
Divide 55 by 15.
So x = 3.66...
Then plug in 3.7 for x in 6x-8
6(3.7)-8
Its approximately 14.2
