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:
The correct answer is option A. r
Step-by-step explanation:
From the figure we can see a circle and a parallelogram.
The circle is divided into a small sectors and these sector then arranged into a parallelogram.
The base of the parallelogram is half the circumference.
The height of parallelogram is equal to the radius of the given circle. Here radius is 'r'.
Therefore the correct answer is option A. r

Answer:
No solution
Step-by-step explanation:
A = (b1 + b2)h/2
A = 35 cm²
h = 16 cm
b1 = 25 cm
b2 = ?
35 = (25 + b2)(16)/2
70 = (25 + b2)(16)
70 = 400 + 16b2
16b2 = 330
b2 = 330/16 = -20.625
The answer is a negative number. Since the base of a trapezium cannot have a negative length, there does not exist a trapezium with the given information.
