I multiplied 17.5 times 2.48 and got 43.4
we are given
it's factor as (x+p)(x+q)
so, we can write as
we can simplify it
now, we can compare both sides
coefficient of x must be equal
so, we get
now, we can look at the table where p+q =3
so, we can see that when p+q=3 .... then p=-2 and q=5
so, option-A.......Answer
The answer is 2(2m+5) for 4m+10 & I can't solve the other one, sorry.
divide distance by time
32 /1.25 = 25.6 miles per hour
Answer:
Step-by-step explanation:
You know the intercepts occur at x = 0, so set each part of the factored form equal to zero and solve for x.
The first part, plain X = 0, so X = 0 is a root, an x-intercept
The second part (X-2)^2 = 0, so X = 2 is another root. Since the function is being squared, this root will happen twice. The function crosses this root twice.
The third part (x+4) = 0, so x = -4 is another root.
Finally, (x+1) so x = -1 is another root.
So you have X = 0, X = 2, X = -4, X = -1 as your x-intercepts
