The factors of the equation $x^2-3x-18$ are $(x-6)(x+3)$

Step-by-step explanation:

We need to factor the quadratic trinomial. $x^2-3x-18$

We will do factorization by braking the middle term such that adding those number we get middle term (-3x) and multiplying those numbers we get (-18x^2)

Solving:

$x^2-3x-18\\=x^2-6x+3x-18\\=x(x-6)+3(x-6)\\=(x-6)(x+3)$

So, the factors of the equation $x^2-3x-18$ are $(x-6)(x+3)$

Carlos has scored 83, 81, and 73 on his previous three tests. What score does he need on his next test so that his average (mean

disa [49]

Answer:

Step-by-step explanation:

let x be his mark in the fourth test, then

mean = $\frac{83+81+73+x}{4}$ = 83 ( multiply both sides by 4 )

83 + 81 + 73 + x = 332

237 + x = 332 ( subtract 237 from both sides )

x = 95

Pls help me i dont know how to do it

I would start by multiplying both sides of the inequality by 4 to eliminate the fraction

y + 8 >/= 12
Then subtract 8 from both sides
y >/= 4

Because it is greater than OR equal to, when you graph, you use a solid circle. Greater than means the arrow goes to the right on the line.

So, solid circle on the line on 4, arrow pointing to the right. (Third option from the right)
