Use the distributive property backwards.
xp+yp=z become p(x+y)=x, which solves to p=x/(x+y)
Answer:
The unknown number is 
Step-by-step explanation:
Let's make the unknown number x.
The sum of 5 TIMES a number (x) & 8 is 9.
Let's write it mathematically.
5x + 8 =9
We are trying to find the unknown number, so let's remove all the numbers from the left side to find x. Minus 8.
5x=1
5x is basically 5 times x, so to find x, we need to divide and from there we can remove 5.
x= 
B is the answer i believe
Answer:
∠BJK ≅ ∠CFH
Step-by-step explanation:
∆BJK ≅ ∆CFH then we say ∠BJK ≅ ∠CFH
Only when we say ∠BJK ≅ ∠CFH we can say (expand) and speak of lengths by comparing two of each ∠BJA ≅ ∠AFC whilst ∠BK≅ ∠ HC then repeat with∠BKJ ≅ ∠CHF etc.
