<h2>x = -6, x = -4</h2>
Step-by-step explanation:
Step-by-step explanation:
(log 0.04 − 2 log 0.3) / (1 − log 15)
<em>Change 1 to log 10.</em>
(log 0.04 − 2 log 0.3) / (log 10 − log 15)
<em>Use log property: a log b = log bᵃ.</em>
(log 0.04 − log 0.09) / (log 10 − log 15)
<em>Use log property: log a − log b = log (a/b).</em>
log (0.04/0.09) / log (10/15)
<em>Reduce fractions.</em>
log (4/9) / log (2/3)
<em>Change 4/9 to (2/3)².</em>
log ((2/3)²) / log (2/3)
<em>Use log property: log bᵃ = a log b.</em>
2 log (2/3) / log (2/3)
<em>Divide.</em>

To find out how many did not raise money, we need to find the percentage that did not raise money and multiply that by the total number of members.
If 95% raised money, 5% did not raise money.
0.05 x 80 = 4 members did not raise money
Step-by-step explanation:
The shape of quadrilateral ABCD changes as the moving platform swings around, but its side lengths do not change. Both pairs of opposite sides are congruent, so ABCD is a parallelogram by the Parallelogram Opposite Sides Converse. By the definition of a parallelogram, — AB — DC .
