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.
-9.24 x 10^-5. Scientific notations requires the front number to be between 1-10 and when you move 5 places over, it becomes -9.24
Answer:6

The base of triangle is 24 inches whose area is 2.75 sq. feet
<u>Solution:</u>
Given, area of a triangle is 2.75 square feet and its height is 33 inches.
We have to find its base length in inches.
So let us convert area units from feet to inches.
Area = 2.75 square feet = 2.75
ft
ft
= 2.75
12 inches
12 inches
[since 1 foot = 12 inches
]
= 2.75 x 144

Area = = 396
Area of triangle is given as:


Hence, the base of the triangle is 24 inches
