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)
Answer:
The answer that you are going to get is 23.56
Step-by-step explanation:
You solve that by multiplying all the numbers and then you divide by 2.
Answer:
The answer is 10 inches, because first we multiply the letters and how wide they are then subtract that from 60 then divide that by our spaces (4)
Step-by-step explanation:
Answer:
The actual length of the wall is 10.5 m
Step-by-step explanation:
Write and solve an equation of ratios to answer this question:
2 cm 3 m
--------- = ---------
7 cm L
Solve this for L by inverting both sides:
7cm L
---------- = --------
2 cm 3 m
and then multiplying both sides by 3m:
21
----- = L
2
The actual length of the wall is 10.5 m
6x+4=-11
6x=-15
X=-15/6
X=-2.5
