Subtract k from both sides of problem
X+k-k = w+v-k
X= w+v-k
By determining the length of TV using TV^2=15^2+10^2-2(15)(10)cos80, and then determining the value of x using 15^2=TV^2+10^2-2(TV)(10)cosx.
Answer:
-2x³ + x² - 3x - 15
Step-by-step explanation:
Simply combine like terms together:
-5x² - 3x - 7 - 2x³ + 6x² - 8
-2x³ + (-5x² + 6x²) - 3x + (-7 - 8)
-2x³ + x² - 3x + (-7 - 8)
-2x³ + x² - 3x - 15
11-
Taking y to the other side;
11-3-6x=
8-6x=
Multiply each side by 2
16-12x=y
y=16-12x
Answer:
x=8
