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.
x-(3x+4)=34
x= -19
-19-(3(-19)+4)=34
-19+(57-4)=34
-19+(53)=34
-19+53=34
34=34
therefore the first number is -19 and the second number is 53
Mean is 8
you have to add all the numbers and then divide it by the number of elements you have in this case 7
H/1000 = tan(65°)
h = 1000*tan(65°) ≈ 2145 . . . . ft
The helicopter is about 2145 ft high.
7/3 +3(2/3 -1/3)^2 =
2/3 -1/3 = 1/3 now you have
7/3 +3(1/3)^2
1/3^2 = 1/9
7/3 +3(1/9)
3*1/9 = 1/3
7/3 + 1/3 = 8/3, which can be changed to 2 2/3
