It is 180 - 65
Which is 115 which would be your answer
3x6=18 3x4=12 12+18=30 so the actual area is 30
Step-by-step explanation:
2x = x1.2^n
2 = 1.2^n
log1.2(2) = n
log10(2)/log10(1.2) = n = 3.801784017...
so, rounded to the next whole year it takes 4 years.
Answer:
16. x = 3.0822, -3.0822
17. x = 1.6432, -1.6432
18. x = 1, -1
Step-by-step explanation:
16. log5[(4x²+2)/8] = 1
(4x²+2)/8 = 5¹
4x² + 2 = 40
4x² = 38
x² = 38/4
x² = 19/2
x = +/- sqrt(19/2)
x = 3.0822, -3.0822
17. log7[(2x²-4)(5)] = 1
10x² - 20 = 7¹
10x² = 27
x² = 2.7
x = +/- sqrt(2.7)
x = 1.6432, -1.6432
18. log5[(2x²+8)/2] = 1
x² + 4 = 5¹
x² = 1
x = +/-1
Answer:
9/15=3/5=0.6
Step-by-step explanation:
how many 5 in 3, 0
how many five in 30, 6
answer is 0.6
