Answer:
Theoretical probability is what that you expect to happen to you while experimental is what actually happen when you try it out.
Let us take 'a' in the place of 'y' so the equation becomes
(y+x) (ax+b)
Step-by-step explanation:
<u>Step 1:</u>
(a + x) (ax + b)
<u>Step 2: Proof</u>
Checking polynomial identity.
(ax+b )(x+a) = FOIL
(ax+b)(x+a)
ax^2+a^2x is the First Term in the FOIL
ax^2 + a^2x + bx + ab
(ax+b)(x+a)+bx+ab is the Second Term in the FOIL
Add both expressions together from First and Second Term
= ax^2 + a^2x + bx + ab
<u>Step 3: Proof
</u>
(ax+b)(x+a) = ax^2 + a^2x + bx + ab
Identity is Found
.
Trying with numbers now
(ax+b)(x+a) = ax^2 + a^2x + bx + ab
((2*5)+8)(5+2) =(2*5^2)+(2^2*5)+(8*5)+(2*8)
((10)+8)(7) =(2*25)+(4*5)+(40)+(16)
(18)(7) =(50)+(20)+(56)
126 =126
Answer:
I cant give you an answer but hints:
First you gotta know the angles of the triangle
then how many are there
then those lines in the middle is dividing lines so
right angles are 90 degrees
I would go for B then.
if not I'm sorry
Answer:
B. 143
Step-by-step explanation:
11 b
----- = -------
12 156
using cross products
11 * 156 = 12 b
divide by 12
11 * 156/12 = b
11 * 13 = b
143 = b
