At first let's multiply the second terms of the given expression. So,
(8-3i)(8+8i) = 8*8 +8*8i - 3i*8 -3i*8i
= 64 + 64i -24i -24i^2 (By multiplying)
= 64 +40i -24*(-1) (Adding the like terms and i^2=1)
=64 +40i +24 (Since (-24)*(-1)= +24)
= 88+40i (Adding the like terms).
Now the original equation is :
(8-3i) - (8-3i)(8+8i) = (8-3i)-(88+40i)
=8 - 3i -88 -40i
=(8-88)-3i -40i (By grouping the like terms)
=-80 -43i (Combine the like terms).
So, the value of the given expression is -80 -43i.

V1 :V2= 250 : 686 =125 : 343 , Volume ratio= 125: 343
r1: r2 = ∛125 : ∛243 = 5 : 7 , Scale factor =5:7
S1:S2 = 5² : 7² = 35 : 49, Surface area ratio =35 : 49
Scale factor =5:7
Surface area ratio =35 : 49
Volume ratio= 125: 343
Answer:
i think your answer is two times the sum of x and seven plus ten
if i am wrong than tell me

Answer: A) 18(1.15)x
Step-by-step explanation:
18 was the original cost, so the price will always be determined with this starting point. Sice there is an increasing value, that makes it 1.15 instead of .15. And it goes up by 15%, making it the coefficient.
