x + x + 3
= 2x + 3.
Answer:
The answer is 21,600. If it travels 6 miles per second that in a minute it would travel 360 miles. You multilpy 360 times 6 and you get your answer of 21,600 miles.
Step-by-step explanation:
By looking at the bottom length of both triangles, we can determine the scale from one to the other.
C-E = 30 units
D-F = 28 units
This can be translated as the fraction 15/14.
So if we look back at the possible answers, both B and C are likely candidates for being the answer.
But to get the answer, we multiply 24 X (15/14).
Which is 25.7, or 25 and 5/7. Your answer is C.
Answer:
2x2+9x−1=x
Step 1: Subtract x from both sides.
2x2+9x−1−x=x−x
2x2+8x−1=0
Step 2: Use quadratic formula with a=2, b=8, c=-1.
x=
−b±√b2−4ac
2a
x=
−(8)±√(8)2−4(2)(−1)
2(2)
x=
−8±√72
