X^2+9x+24=0 i believe, i’m only in 7th grade so
also, you factor the equation equal to zero and factor the left side
<span>In a right triangle, we know that we have one angle that is 90 degrees. In order to calculate the length of the adjacent side we have to use the cosine function of angle C which will give us the adjacent side length. The cosine function is: adjacent/hypotenuse = cos (40). We know the hypotenuse length is 10, so the equation is now adjacent/10 = cos (40). Solving for adjacent length we get 7.66 inches.</span>
They both equal 87 and the property is commuting property

Answer:
9/16
Step-by-step explanation:
After the first exchange the amount in dollars is ...
£320 × $1.25/£1 = $400
After the spending, the amount in dollars is ...
$400 -100 = $300
After the second exchange, the amount in pounds is ...
$300 × £0.60/$1 = £180
This amount is 180/320 = 9/16 of the original amount.
