Step-by-step explanation:
The last step is a little wrong. Lemme show you:
x(x + 2) + (x + 2)
Imagine there is an invisible '1' infront of (x + 2) like this:
= x(x + 2) + 1(x + 2)
Now we can combine the like terms together:
= (x + 1)(x + 2)
This is the correct factorization.

The area of triangles is 1/2 x b x h.
Plug them in!
1/2 x 24 x 35
Simplify.
12 x 35
420 square inches
Answer:
5 1/3
Step-by-step explanation:
Set up ratio.
2/3 cup orange juice X 2 cups pineapple juice
———————————-
1/4 cup pineapple juice
first multiply numerator : 2/3 x 2 = 4/3
and divide by denominator
(4/3)/(1/4). Keep the first. Change the sign to multiplication and Flip the second fraction.
4/3 x 4/1 = 16/3
change to proper fraction : 16/3 = 5 1/3 cups
X^2+5x=2
you then solve by completing the square using the formula (b/2)^2 in order to create the new term. Solve for x by using this term to complete the square.
Your answer is then
x=-5/2+-√33/2
