D -9 because it has a -3 and its going to be the same - sign
Diagonals of a rectangle are congruent.
18x - 28 = x + 380
Solving for x, I get 17.
So, x = 17.
PR = 18x - 28
PR = 18(17) - 28
PR = 278
QS = x + 380
QS = 17 + 380
QS = 397
Answer:
46,125
Step-by-step explanation:
2.5% = .025
45,000 * .025 = 1,125
45,000 + 1,125 = 46,125

Answer:
a) below
b) log_35 (8) = x
c) x = 0.58487
Step-by-step explanation:
a) 35^x=8
<em>apply the exponent rule</em>
xln(35) = ln(8) → x = ln(8)/ln(35) → x = 3ln(2)/ln(35)
x = 0.58487
c) log_35 (8) = x
x = log_35 (8)
<em>base form (Rewrite 8 in power)</em>
x = log_35 (2^3)
<em>log rule: log_a(x^b) = b*log_a(x)</em>
log_35 (2^3) = 3log_35(2)
x = 3log_35(2)
x = 0.58487
