$\\ \sf\longmapsto 2x^2c^2+3xc^2-35c^2$

Take c^2 common

$\\ \sf\longmapsto c^2(2x^2+3x-35)$

Factor the brackets

$\\ \sf\longmapsto c^2(2x^2+10x-7x-35)$

$\\ \sf\longmapsto c^2(2x(x+5)-7(x+5))$

$\\ \sf\longmapsto c^2(2x-7)(x+5)$

Answer:

c²(x + 5)(2x - 7)

Step-by-step explanation:

2x²c² + 3xc² - 35c² =
c²(2x² + 3x - 35) =
c²(2x² + 10x - 7x - 35) =
c²(2x(x + 5) - 7(x + 5)) =
c²(x + 5)(2x - 7)

An oil-drilling company knows that it costs $25,000 to sink a test well. If oil is hit, the income for the drilling company will

Answer:

The expectation for the drilling company is $8,375.

Step-by-step explanation:

We have that the expectation for the drilling company is:

$E = E_{1} + E_{2} - 25,000$

$E_{1}$ is the income that is expected in relation to natural gas being hit. There is a 1/20 probability that gas is hit. If gas is hit, the income will be $260,000. So

$E_{1} = \frac{260,000}{20} = 13,000$

$E_{2}$ is the income that is expected in relation to oil being hit. There is a 1/40 probability that oil is hit. If oil is hit, the income will be $815,000. So

$E_{2} = \frac{815,000}{40} = 20,375$

25,000 is subtracted from the expectation because it is the cost to sink a test well.

So,

$E = E_{1} + E_{2} - 25,000 = 13,000 + 20,375 - 25,000 = 8,375$

The expectation for the drilling company is $8,375.

A total of 408 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student t

Lisa [10]

Ok..So.. we will make this notation adult tickets= x and student tickets=y. It says that the number of student tickets was 2 times the number of adult tickets, so.. y=2x. x+y=408 (the total number)=> x+2x=408. 3x=408 => x=408/3 => x=136. (the number of adult tickets)
