Answer:
9 sq.m
Step-by-step explanation:
because the area of triangle is 1/2 *b*h
Answer:
8^-32
Step-by-step explanation:
<h3>Given</h3>
A(-3, 1), B(4, 5)
<h3>Find</h3>
coordinates of P on AB such that AP/PB = 5/2
<h3>Solution</h3>
AP/PB = 5/2 . . . . . desired result
2AP = 5PB . . . . . . multiply by 2PB
2(P-A) = 5(B-P) . . . meaning of the above
2P -2A = 5B -5P . . eliminate parentheses
7P = 2A +5B . . . . . collect P terms
P = (2A +5B)/7 . . . .divide by the coefficient of P
P = (2(-3, 1) +5(4, 5))/7 . . . . substitute the given points
P = (-6+20, 2+25)/7 . . . . . . simplify
P = (2, 3 6/7)
3.1,3.2,3.3,3.4,3.5,3.6,3.7,3.8
9.327 rounds to 9.3
5.72 rounds to 5.7
4132 rounds to 4132
9.3 + 5.7 + 4132 =
15 + 4132 = 4147
