Answer:
Step-by-step explanation:
Step 1: Subtract 10 from both sides.
2x2+20x−10=10−10
2x2+20x−10=0
For this equation: a=2, b=20, c=-10
2x2+20x+−10=0
Step 2: Use quadratic formula with a=2, b=20, c=-10.
x=
−b±√b2−4ac
2a
x=
−(20)±√(20)2−4(2)(−10)
2(2)
x=
−(20)±√(20)2−4(2)(−10)
2(2)
x=
−20±√480
4
x=−5+√30 or x=−5−√30
Answer:
x=−5+√30 or x=−5−√30
She either had $0.52 or more because it doesn’t say how many erasers she got
F + 0.3 < 1.7
Subtract 0.3 on both sides
F < 1.4
Your final answer is F < 1.4
The height would be the same as the rectangular piece of paper as well as the length so what you would do is you do heights times Lanks divide that by two and you would get the Square inches of the banner hope it helps
Hold before I need to answer is this math or science, I need to know which one to write.
