Answer:
30
Step-by-step explanation:
The formula for finding the area of a triangle is b/2 x h
b = 5
h = 12
5 ÷ 2 = 2.5
2.5 x 12 = 30
The area of the triangle is 30 m

Answer:
A
Step-by-step explanation:
P rose selected both times =
P rose selected the first time and P rose selected the second time
in probability and =multiplication
P rose selected the first time = number of roses/ number of flowers = 3/ 8
P rose selected the second time = 3/8 is the same as before since the flower was put back
P rose selected both times = (3/8)·(3/8) = 9 /64
In this problem, two binomials are being multiplied.
First, you see the First terms multiplied together, x^2 and -5x^2.
Then you see the Outside terms multiplied together, x^2 and x.
Next, you see the Inside terms multiplied together, -2 and -5x^2.
Finally, the Last terms are multiplied together, -2 and x.
Put together the bold letters above and you spell FOIL.
FOIL is a way to remember how to multiply two binomials.
F - multiply the First terms.
O - multiply the Outside terms.
I - multiply the Inside terms.
L - multiply the Last terms.
In general, to multiply to binomials
(a + b)(c + d) =
F: ac
O: ad
I: bc
L: bd
= ac + ad + bc + bd
Answer: Choice A. FOIL
