Answer:
12
Step-by-step explanation:
x + y = 6 and xy =2
Left sides multiplied= right sides multiplied
Multiply (x+y) by xy = 6*2
(x+y) xy = 6*2
Distribute
x^2y + xy^2 = 12
Answer:
A:38 c:54
Step-by-step explanation:
First off, I did the easiest which was a. i found the value of A by subtracting 180 by 142. because a flat line is 180 degrees.
For C, It was more difficult. I subtracted 88 by the value of A, since the value of A is the same as the one next to 88. So I subtracted 126 (88+38) and got 54.
Fortunately, I couldn't figure out B though, but i think it is a similar answer to c.
U don't wanna write but I am 90+50/6-5 Inna do the rest in comments
Answer:
(3 + 2x) + (4 – 5x) = 7 - 3x
(3 + 2i) + (4 – 5i) = 7 - 3i
Step-by-step explanation:
In the addition of two binomials you have to add separately each monomial as follows:
(3 + 2x) + (4 – 5x) =
= (3 + 4) + (2x - 5x) =
= 7 - 3x
Analogously, the sum of the complex numbers 3 + 2i and 4 – 5i is made adding the two real parts from one side, and the two imaginary parts from the other side, as follows:
(3 + 2i) + (4 – 5i) =
= (3 + 4) + (2i - 5i) =
= 7 - 3i
