Answer:
Option d
Step-by-step explanation:
given that a, b, c, and d be non-zero real numbers.
we can factorise this equation by grouping
Equate each factor to 0 to get
Ratio of one solution to another would be
So ratio would be ad/bc
Out of the four options given, option d is equal to this
So option d is right
Answer:
x=2
Step-by-step explanation:
After solving with substitution, you would know x = 2
Compatible numbers are known as
numbers that are the closest value to the actual numbers- this makes mental
arithmetic to be performed better. The quotient of 358/3 is equal to 119.333 therefore
the compatible number of the quotient of 358/3 is 119.
We have that
a-b=0-----------------> a=b
b=a
therefore
a.b--------> substituting---------> a*(a)=a² or b*b=b²
the answer is the option A) a²
Answer:
3πx³ + 20πx² + 44πx + 32π
Step-by-step explanation:
Volume of a cylinder = πr²h
Where,
r = radius of the cylinder
h = height of the cylinder
r = x+2
h = 3x + 8
Volume of a cylinder = πr²h
= π × (x+2)² × 3x + 8
= (3xπ + 8π) × (x + 2)²
= (3πx + 8π) + (x² + 4x + 4)
= 3πx³ + 12πx² + 12πx + 8πx² + 32πx + 32π
= 3πx³ + 20πx² + 44πx + 32π
Note:
(x + 2)²
= (x + 2) (x + 2)
= x² + 2x + 2x + 4
= x² + 4x + 4
