Answer:
(6a + 5b)(6a - 5b)
Step-by-step explanation:
Rewrite the expression in the form of a² - b²:
(6a)² - (5b)²
Use the difference of squares (a² - b² = (a + b)(a - b)):
(6a + 5b)(6a - 5b)
Answer:
130
Step-by-step explanation:
first find angle C, which is 180-90-40=50
angle Y=180-50=130
Answer:
D
Step-by-step explanation:
y=2x²+2x+1.... i
y=2x+3......... ii
Equating i and ii,
2x²+2x+1=2x+3
2x²+1-3=0
2x²-2=0
x²-1=0
x=1 or -1.
From ii, if x=1,y=5
If x=-1, y=1.
The points are (-1,1) and (1,5)
