172.9
You find it by multiplying each side of the triangle by the height (9) and adding the results together.
A(lateral) = 8 * 9.1 + 3 * 9.1 + 8 * 9.1
= 72.8 + 27.3 + 72.8
= 172.9
Answer:
x=3 and x=-1.25
Step-by-step explanation:
4x^2-7x=15
subtract 15 from each side:
4x^2-7x-15=0
factor (trying different numbers that the sum is 7 and the quotient is 15)
(2x-6 )(2x+2.5 )=0
2x-6=0 add 6 to each side
2x=6
x=3
2x+2.5=0 subtract 2.5 from each side
2x=-2.5
x=-1.25
Step-by-step explanation:
singkamas: 60 pesos
ponkan: 110 pesos
1045 = 1000 since 45 is not near 2000
6589 = 7000
Near to low: 0, 1, 2, 3, 4
Nearer to High: 5, 6, 7, 8, 9
I hope this helps you
10B=6-12C
B=2 (3-6C)/10
B =3-6C/5
