Answer:
Let us take 'a' in the place of 'y' so the equation becomes
(y+x) (ax+b)
Step-by-step explanation:
Step 1:
(a + x) (ax + b)
Step 2: Proof
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
Step 3: Proof
(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:
18 miles
Step-by-step explanation:
You can start with the equivalence ...
1/2 in = 3 miles
and multiply it by 6.
6·(1/2 in) = 6·(3 miles)
3 in = 18 miles
Towns that are 3 inches apart on the map are 18 miles apart on the ground.
___
Why 6? because that is the number 1/2 needs to be multiplied by to get 3. Said another way, ...
3/(1/2) = 3·2 = 6
Maybe it’s uhh uhhh 20 feet yuh
I mean cause 2 x 2 is 4
So 2+2 is 4 you’re just putting 2 into 4 twice
