Answer:24v+24w-16
Step-by-step explanation:
8(3v+3w-2)
8 times 3 =24
So 24v+24w
Then 8 times 2=16
So the answer would be 24v+24w-16
Answer:
D. 8/2 +(-10)² = 104
Step-by-step explanation:
To find which statements are true, evaluate the expression for the given variable values. You do this by putting the numbers in place of the respective variables, then doing the arithmetic.
The respective expression values are ...
A 83 ≠ 37 . . . . (4/2) +9² = 2 +81 = 83
B 31 ≠ 61
C 52 ≠ 61
D 104 =104 . . . . true statement

I find it less tedious to write a function into a calculator or spreadsheet and let it do the repetitive math. Examples of the calculation are shown above.
Using the formula (AB +BC) *BC = (DE +CD) *CD
fill i n what is known:
(17 + 4) *4 = (DE +6) *6
21*4 = (DE +6)*6
84 = (DE+6)*6
84/6 = DE+6
14 = DE +6
DE = 14-6
DE = 8
Answer:
a) ![-5x^{2}+3x+27](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B27)
b) ![-5x^{2}+3x+9](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B9)
Step-by-step explanation:
a) Let the required polynomial be p(x).
We have the relation,
+ p(x) = 18
i.e. p(x) = 18 ![-5x^{2}+3x+9](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B9)
i.e. p(x) = ![-5x^{2}+3x+27](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B27)
b) Let the required polynomial be q(x).
We have the relation,
+ q(x) = 0
i.e. q(x) = 0 ![-5x^{2}+3x+9](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B9)
i.e. q(x) = ![-5x^{2}+3x+9](https://tex.z-dn.net/?f=-5x%5E%7B2%7D%2B3x%2B9)
