Answer:
Step-by-step explanation:
Surface area of the triangular prism = 2B + ph
B is the base area = 11 * 14
B = 154 sq. cm
p is the perimeter of the base =
I'm assuming that the 3434 is a typo error. It should be 34.
Marni: 18 + 0.80m
Sharika: 12 + 0.9m
x = Sharika's minutes
x + 34 = Marni's minutes
[18 + 0.80(x+34)] + [12 + 0.90(x)] = 264
18 + 0.80x + 27.2 + 12 + 0.90x = 264
0.80x + 0.90x = 264 - 18 - 27.2 - 12
1.70x = 206.80
x = 206.80/1.70
x = 121.65 or 122
x + 34 = 122 + 34 = 156 minutes.
Finding zeros or setting y ot f(n) equal to zero
and all you have to do is factor it, hoping you know how to do this
5. 0= n^2-2n-15
(n-5)(n+3)= 0
n-5= 0 n+3=0
n=5 and n=-3
6.t^2+6t=27
t^2+6t-27=0
(t + 9) (t-3)= 0
t=-9 and t=3
7. x^2-9x=-18
x^2-9x+18=0
(x-6)(x-3)= 0
x=6 and x=3
8. a^2 - 7a = 30
a^2 - 7a -30= 0
(a-10)(a+3)=0
a=10 and a=-3
hope that helps
