Answer: A
Step-by-step explanation:
Treat the real and imaginary parts separately, then combine. Because it is addition, not subtraction, distributing the sign will not make a difference. Remove the parenthesis and group like terms together. Then simplify and put in standard form for imaginary numbers (real first, then imaginary).

The United States Congress contains 435 representatives and 100 senators. You want to make groups that each have the same number of representatives and senators. What is the greatest number of groups you can make?
Answer:
5
Step-by-step explanation:
The greatest common factor of 435 and 100 is 5, so if you make 5 groups, each group will have 87 representatives and 20 senators.
Write an equation of a line that goes thru the points (-2, 6) & (3, -4)
Answer:
y= -2x +2
Step-by-step explanation:
The equation of a line can be written in the form of y= mx +c, where m is the gradient and c is the y-intercept. This form is known as the slope-intercept form.
To find the value of m, use the gradient formula below:
[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]
[tex]m = \frac{6 - ( - 4)}{ - 2 - 3}[/tex]
[tex]m = \frac{6 + 4}{ - 5} [/tex]
[tex]m = \frac{10}{ - 5} [/tex]
m= -2
Substitute m= -2 into the equation:
y= -2x +c
To find the value of c, substitute any pair of coordinates that the line passes through into the equation. Here, I am going to substitute the coordinates (3, -4).
y= -2x +c
When x= 3, y= -4,
-4= -2(3) +c
-4= -6 +c
c= -4 +6
c= 2
Thus, the equation of the line is y= -2x +2.
Find the measure of each exterior angle of a regular polygon in which the sum of the measures of the interior angles is 2,520 degrees.
Answer:

Step-by-step explanation:
Find the measure of side b. Round to the nearest whole number.
9514 1404 393
Answer:
143 m
Step-by-step explanation:
The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(33°) = b/(170 m)
b = (170 m)cos(33°) ≈ 142.57 m
The measure of side b is about 143 meters.

Write an equation of a line through the point (-4,-1) that is parallel to the line y= -3/4x + 4
Answer:
y = -3/4x -4
Step-by-step explanation:
Parallel slope = -3/4
(-4,-1)
y - y1 = m(x - x1)
y + 1 = -3/4(x + 4)
y + 1 = -3/4x - 3
y = -3/4x -4

f(n)=45⋅(4/5)^n−1
complete the recursive formula of f(n)
F(1) = 45
f(n) = f(n-1) * 4/5
Step-by-step explanation:
f(n) = 45 x (4/5)ⁿ⁻¹
f(1) = 45 x (4/5)¹⁻¹ = 45 x (4/5)⁰ = 45 x 1 = 45
f (n-1) = 45 x (4/5)ⁿ⁻¹⁻¹ = 45 x (4/5)ⁿ⁻²
f(n) = f(n-1) * (4/5)¹ = 45 x (4/5) ⁿ⁻²⁺¹ = 45 x (4/5)ⁿ⁻¹
Answer:
45

The sum of any two sides must be greater than the other to be it triangle thus it will not be a triangle so option (D) is correct.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180°.
For any triangle, the sum of any two sides must be greater than the then third side.
As per the given sides, 11, 13, 25
11 + 13 < 25
24 < 25 so it will not a triangle.
Hence "The sum of any two sides must be greater than the other to be it triangle thus it will not be a triangle".

Answer:
let X interchange y and vice versa
X= 2x+3

X-3=2X
carry across 2 (2X is 2 multiple by X when carried across the sign change to division)
so X-3 divided by 2 is = X
