4x - 8, 4x just means four of x, and eight less means to subtract 8.
Answer:
4x - 16
Step-by-step explanation:
A triangle is a three sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
the perimeter of a triangle = sum of the side lengths
let the unknown length be represented with y
13x - 21 = 4x + 3 + 5x - 8 + y
13x- 21 = 9x - 5 + y
Make y the subject of the formula
13x - 21 - 9x + 5 = y
4x - 16 = y
the side length = 4x - 16
Answer:
Step-by-step explanation:
the solution to the system
= find the intersection of two lines
method( one )
solve the equations ( find(x , y) )
( 1 ) y = -x +3
( 2 ) y = x - 3
now , we let ( 1 ) + (2 )
we have 2y =0 ,thus y = 0
from ( 1 ) y = - x +3 , we know y = 0 ,
we rewrite ( 1 ) as 0 = -x + 3,thus x = 3
method( two)
see the intersection point of two lines
so the ans is B.(3 , 0)
Answer:
D. -2.6-(-12) is positive
C.(-3.7)+(-12) is Positive
A. +(-2.5) is negative
Answer:
c) 2x⁵ + 11x³ - 5x²
Step-by-step explanation:
f(x) - g(x) = 2x⁵ + 7x³ - (-4x³ + 5x²)
= 2x⁵ + 7x³ + 4x³ - 5x²
= 2x⁵ + 11x³ - 5x²
