Step-by-step explanation:
4x2+8x−3=0
For this equation: a=4, b=8, c=-3
4x2+8x+−3=0
Step 1: Use quadratic formula with a=4, b=8, c=-3.
x=
−b±√b2−4ac
2a
x= −(8)±√(8)2−4(4)(−3)
2(4)
x= −8±√112
8 x=−1+
1 2 √7 or x=−1+
−1 2 √7
Answer: x=−1+
1 2√7 or x=−1+
−1 2 √7
Answer:
19x−47
Step-by-step explanation:
19x+−25+21+−43
You gotta combine the like terms
(19x)+(−25+21+−43)
19x+−47
Answer:
100degrees or D
Step-by-step explanation:
One hack is recognizing that
x% of 100 is x
150 is 1.5 times of 100 so
x% of 150=1.5x
therfor
12.5% of 150=1.5*12.5=18.75
anyway
percent means parts out of 100
12.5%=12.5/100=0.125
'of' means multiply
12.5% of 125=0.125*150=18.75
the answer is 18.75
