Answer:
2p + 99q
Step-by-step explanation:
To simplify the expression, combine the like terms. Like terms are terms which have the same variable. Assume 00q is 100q.
6p - 3q + z - 3p + 2q - z - p + 100q
6p - 3p - p = 2p
- 3q + 2q + 100q = 99q
z - z = 0
So the expression is 2p + 99q
Answer:
coefficient of x: 2
coefficient of y: 3
coefficient of z: -7
Step-by-step explanation:
To solve this problem, first we need to sum the polynomials A and B, then we need to check the coefficients of x, y and z.
The sum of the polynomials is:
A + B = 5z + 4x^2 - 6y + 2 + 2x + 9y - 12z - 2
A + B = 4x^2 + 2x + 3y - 7z
So, the coefficients are:
coefficient of x^2: 4
coefficient of x: 2
coefficient of y: 3
coefficient of z: -7
Answer:
90°
Step-by-step explanation:
5x+20=9x
20=9x-5x
20=4x
x=5
5x+20+9x=
5(5)+20+9(5)=
25+20+45=
90
