Answer:
2x + y -6 = 0
Step-by-step explanation:
The general form is 
. It requires that A and B be greater than 1 (not fractions or decimals) and A is positive. This equation is 2x + y = 6 is almost already in the form. Subtract C to both sides to make it general form. 2x + y - 6 =0. The coefficients of the x and y are greater than 1 and 2 is positive. This meets the requirements.
Answer:
30 x 5x
9x + 5y
8x+ 20y
Step-by-step explanation:
Answer: 39
Step-by-step explanation:
Given
P(x)=7x+5
r(x)=x-1
r(p(x))=7x+5-1=7x+4
so, r(p(5))
Answer:
4ab
Step-by-step explanation:
(a+b)^2-(a-b)^2
=a^2 + 2ab + b^2 -(a^2 - 2ab +b^2)
=a^2 + 2ab + b^2 - a^2 + 2ab - b^2
=2ab + 2ab
=4ab
Answer:
480 mm³
Step-by-step explanation:
The volume (V) of a pyramid is
V = 
area of base × height, hence
V = × 96 × 15 = 32 × 15 = 480
