<h2>
Answer:</h2>
Ryan is 23 and Naomi is 17.
<h2>
Step-by-step explanation:</h2>
Find the midpoint of 40. This is 40/2, or 20.
Because the difference in age is 6, but the total of the ages must add up to 40, you must also halve 6. 6/2 is 3.
Take away three and add three to 20.
20 + 3 = 23. This is Ryan's age as he is the older sibling.
20 - 3 = 17. This is Naomi's age.
Answer:
The first thing you ever do when simplifying an expression is distributing the coefficient. For example the expression 3(5x+6+4x) The first thing we would do is distribute the 3 into each value in the parantheses. It would make sense to add the 4x and 5x, but that goes out of order. This is just the rules when it comes to follwing distributive property in it's simplest form.
P(-5) = (-5)³ - 6(-5)² - 7(-5) + 60
p(-5) = -125 - 6(25) - (-35) + 60
p(-5) = -125 - 150 + 35 + 60
p(-5) = -275 + 95
p (-5) = -180
so is x + 5 a factor of polynomial ( NO) because when make a substitution by -5 the answer will not be 0
Answer:
(2x+5)(-3x+7)
-6x^2-15x+14x+35
-6x^2-x+35
So, the last option is the correct answer.
