Answer:
(2x² + 5x + 2) = (2x + 1)(x +2)
Step-by-step explanation:
Given expression is (2x² + 5x + 2).
We have to factorize the given expression.
(2x²+ 5x + 2) = 2x² + 4x + x + 2
= 2x(x + 2) + 1(x + 2)
= (2x + 1)(x + 2)
So the factored form of the given expression will be (2x + 1)(x + 2).
R = = 3.6 and A = 2
given that R is inversely proportional to A, then
R = ← k is the constant of variation
To find k use the condition R = 12 when A = 1.5
k = RA = 12 × 1.5 = 18
the equation is therefore
R =
when A = 5, then
R = = 3.6
when R = 9, then
9 = ( multiply both sides by A )
9A = 18 ( divide both sides by 9 )
A = 2
Answer: 7pi/18

Answer:
Step-by-step explanation:
make y=0
0=-2x+3 (Switch the 3 sides)
-3=-2x (Divide everything by -2, cant have a negative x)
2/3=x or 0.66=x
Use the following:
HI = (1/2)(KL + MN)
5x + 2 = (1/2)(4x + 1 + 27)
5x + 2 = (1/2)(4x + 28)
5x + 2 = 2x + 14
5x - 2x = 14 - 2
3x = 12
x = 12/3
x = 4
However, the value of x is not the distance KL. We now evaluate KL at x = 4.
KL = 4x + 1
KL = 4(4) + 1
KL = 16 + 1
KL=17
The answer is choice D.
