<em>Greetings from Brasil...</em>
According to the question of the statement, we can conclude that
PQ = 2B
QR = 2B
PR = base = B
Perimeter = P = 105
P = PQ + QR + PR
105 = 2B + 2B + B
B = 21
<h2>PQ = 2B = 42</h2><h2>QR = 2B = 42</h2>
<span>distributive property
</span><span>B. −3⋅(6.48)=(−3⋅6)+(−3⋅0.4)+(−3⋅0.08) </span>
Do as the apples goes up in 4s
3 7 11 the goes 3 +4 = 7, 7+4 = 11
and Sees goes up in 40's
30 70 110
and rate of change is

its 40/4 or 10/1 (that's the first one)
8/1600 as a percentage is 0.5%
