Hello!
First off, please write y2 + y as y^2 + y. The " ^ " symbol denotes exponentiation, whereas y2 is meaningless.
To find the constant term in question, take half of the coefficient of y (that is, take 1/2) and square it. Then we have y2 + y + 1/4.
The constant term in question is 1/4.
(5+4+6-2)×2×2-1
(9-4)×2×2-1
5×2×2--1
10×2-1

Answer:
x = 45
Step-by-step explanation:
Solution:
x - y = 30
x - 15 = 30 ( y = 15 given)
x = 30 + 15
Therefore, x = 45

Well first you take 78 and turn it to 7.8
then multiply by 10000
therefore 7.8*10000= ?
