14(12)+5(6)+16 = 168+30+16=214
This is the correct formula for the problem because you sold 12 maracas, 6 calves, and 1 single drum. You should also put the parenthesis next to the numbers that are being multiplied because you sold multiple of those items.
square root of 16 would be 4
4 x 4 = 16
Answer:
9x = 120
x=
Step-by-step explanation:
x-8°+20°= 90°
=>x+12°=90°
=>x=90°-12°
=>x= 78°
d=-4 and a=10
The sum of a arithmetic sequence is given by (n/2)*(2a+(n-1)d). Comparing coefficients with the given Sn, we have; a-d/2=12 and d/2=-2, d=-4 and a=10.
