498+345 is the answer but you divide the 3 for base of 9
Answer:
Explanation contains the proof.
Step-by-step explanation:
.
.
We want to show that . So we are asked to show that there exist integer
So what is ?
.
.
So back to ....
(I use foil to get this)
Factoring out 8 gives us:
Now I could have factored some 8's out of 25. There are actually three 8's in 25 with a remainder of 1.
We have shown that there is integer .
The integer I found that is n is 8km+5k+5m+3.
Therefore .

Answer:
84
Step-by-step explanation:
Since we are given line OP perpendicular to line DR, then angles PDR and ODR are right angles.
Angles PDA and ADR are complementary.
Angles ODU and UDR are complementary.
Angles ADR and UDR are given as congruent.
We can conclude that angles PDA and ODU are congruent.
By AA Similarity, triangles APD and UMD are similar.
DP/DM = PA/MU
3.75/10 = 4.5/MU
3.75MU = 10 × 4.5
MU = 12 (altitude of triangle DUO)
OD = OM + MD = 4 + 10 = 14 (base of triangle DUO)
area = base × height / 2
area = 14 × 12 / 2
area = 84
