Answer: x=1

Step-by-step explanation:

You need to open up the parenthesis so you multiply every term inside the parenthesis by -7.

1. -7x + 14 + 1 = 15 -7x

2. Combine like terms -7x + 15 = 15-7x

The two sides of the equation are the same so that means that x=1

Step-by-step explanation:

40 - x² = 0

Answer:

log_{b} (5b) = 2.609

Given that:

log_{b} (3) = 1.099

log_{b} (5) = 1.609

Evaluating with that:

$\sf log_b (5b) = log_b\left(5\right)+log_b\left(b\right)$

$= \sf 1.609 + 1$

$= \sf 2.609$

Rule Used:

$\rm \log _a\left(xy\right)=\log _a\left(x\right)+\log _a\left(y\right)$
