Answer:
B 18.38
Step-by-step explanation:
log4x = 2.1
logx/log4 = 2.1
logx = log(4) x 2.1
logx = 1.2643
x = antilog(1.2643)
x = 18.38 (to 2 d.p)
Answer:
The answer to all of those questions would be x=-1.8
Step-by-step explanation:
7x(x + 1.8) = 0 - Distribute through the Parenthesis -
7x^2 + 12.6x = 0
x(7x + 12.6) = 0
x = 0
7x + 12.6 = 0
7x = -12.6
x = -12.6/7
x = -1.8
so x = 0 or x = -1.8
5.6 in a fraction is 5 and 6/10, or 5 3/5. To get the mixed fraction, multiply the whole number (to the left) by the denominator (bottom of fraction), and add to the numerator (top of fraction). So 5 × 5 = 25 + 3 = 28. So it'd be 28/5.
You should divide 280 into 3 which would equal 9
