Answer:
A of each triangular base = 6 in²
A of both bases = 12 in²
Lateral A = 96 in²
Surface area = 108 in²
Step-by-step explanation:
<em>Area of each triangular base</em>
1/2(3)(4) = 1/2(12) = 6
<em>Area of both bases</em>
6*2 = 12
<em>Lateral Area</em>
(8)(3) + (8)(4) + (8)(5)
24 + 32 + 40
96
<em>Total Surface area</em>
96 + 12 = 108 in²
.1 repeating is 1/9, so either write it as 12 1/9, or 109/9
B but I may be wrong but I hope I heped
Answer:
When they are equal, y=y, so we can say:
x^2+5x-2=x+1 subtract x from both side
x^2+4x-2=1 add 2 to both sides
x^2+4x=3, now add half the linear coefficient squared, (4/2)^2=4
x^2+4x+4=3+4 now the left side is a perfect square
(x+2)^2=7 now take the square root of both sides
x+2=±√7 subtract 2 from both sides
x=-2±√7
x=-2+√7 and -2-√7
y=x+1 the two points where these equations are equal are:
(-2-√7, -1-√7) and (-2+√7, -1+√7)
or approximately:
(-4.65, -3.65) and (0.65, 1.65)
