To start, first distribute the x's to their expressions. This would look like this:
(x*x+2*x)+(x*x+x*3)=x^2+2x+x^2+3x
Then, you combine like terms or simplify, and you get an answer of 2x^2+5x

Start off by distributing the x to x+2.
X^2+2x
X+x+3

ADD EVERYTHING TOGETHER
X^2+4x+3

lbvjy [14]

Answer:

$midpoint = ( \frac{ - 4 + 6}{2} , \: \frac{ - 12 + 8}{2} ) \\ = (1, \: - 2) \\ \\ distance = \sqrt{ {( - 4 - 6)}^{2} + {(8 + 12)}^{2} } \\ = \sqrt{500} \\ = 22.4 \: units$

Answer:

s= 15 (nearest integer), 14.8 (to nearest 10ths)

Step-by-step explanation:

here you need to apply the cosine rule,

${s}^{2} = {u}^{2} + {t}^{2} - 2ut \cos(s)$

substituting the values,

u= 13, t=5 and angle S as 60 and solving will give you the answer 14.76 (2 dp)

Four ounces of oregano and 2 ounces of garlic powder are mixed to create a poultry seasoning. Oregano costs $4 per ounce and gar

AveGali [126]

There isn't an obvious question to this problem but with the given we can assume what is to be asked. I think we are to find the total cost of a certain poultry seasoning. The poultry seasoning would have a total weight of 4+2=6 ounces. The total cost will then have to be 4(4) + 2(3) = 22 dollars.
