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:
sod- 1662.6
fencing- 807.6
all- 2470.2
Step-by-step explanation:
sod-
25.5 * 8.25 = 207.825
207.825*8= 1662.6
fencing-
8.25+8.25+25.5+25.5= 67.3
67.3*12= 807.6
fencing + sod
1662.6 + 807.6= 2470.2
