Hello!
When multiply binomials together, we should use the FOIL method.
The FOIL method is an acronym for First, Outer, Inner, and Last.
First, let's set up the expression.
(7x - 1)(3x - 2)
Now, we can multiply in accordance with the FOIL method.
First: 7x · 3x = 21x²
Outer: 7x · -2 = -14x
Inner: -1 · 3x = -3x
Last: -1 · -2 = 2
Now, we simplify the inner terms.
21x² - 14x - 3x + 2
21x² - 17x + 2
Therefore, the area of the rectangle is 21x² - 17x + 2.
The y-intercept is (0,7) and the x-intercept is (-2,0).
Answer:
0.7 minute
Step-by-step explanation:
Given that each (1) minute a light use 9.4 watts.
So If the light bulb used a total of 6.58 watts, the minutes was on it is:
= 
= 0.7 minute
So the the minutes was on it is 0.7
Hope it will find you well!
Answer:
-2x - (-5 - 4x) = -5(2x - 7)
-2x + 5 - 4x = -5 * 2x - 5 * (-7)
-6x + 5 = -10x - 35
-6x + 5 + 10x = -10x - 35 + 10x
4x + 5 = -35
4x + 5 - 5 = -35 - 5
4x = -40
4x/4 = -40/4
x = 10
