Answer:
(2x + y)(2x - y - 1)
Step-by-step explanation:
4x² - y² - 2x - y
4x² - y² is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
4x² - y²
= (2x)² - y²
= (2x - y)(2x + y)
expression is now
(2x - y)(2x + y) - (2x + y) ← factor out (2x + y) from each term
= (2x + y)(2x - y - 1)
79 is the length because
292-2(67)= 158
158/2 = 79
Answer: 76 degrees
Step-by-step explanation:
m<abc = m<1 + m<2
4x+12=(2x-7)+(3x-4)
x=23
180=4x+12+m<3
m<3=76
X-intercept = (x,0) y is zero
y- intercept = (0,y) x is zero
In the equation y = -1/2 x -5
x-intercept would be
0 = -1/2 x - 5
5 = -1/2x
x = -10
y-intercept would be
y = -1/2 (0) - 5
y = -5
Thus, the answer is (-10,0) and (0,-5).
