x=9
Answer:
1232 m^2.
Step-by-step explanation:
The net consists of 2 triangles and 3 rectangles.
Area of each triangle = 1/2 * 24*7 .
Area of 1 rectangle = 25 * 19.
The other 2 have areas 24*19 and 7 * 19.
Therefore the surface area of the prism
= 2 * 1/2 * 24 * 7 + 25*19 + 24*19 + 7*19
= 1232 m^2.
Answer:
t = - 3, t = - 1
Step-by-step explanation:
Given
h(t) = t² + 4t + 3
To find the zeros equate h(t) to zero, that is
t² + 4t + 3 = 0
Consider the factors of the constant term (+ 3) which sum to give the coefficient of the t- term
The factors are + 3 and + 1, since
3 × 1 = 3 and 3 + 1 = 4, thus
t² + 4t + 3 = (t + 3)(t + 1) = 0
Equate each factor to 0 and solve for t
t + 3 = 0 ⇒ t = - 3
t + 1 = 0 ⇒ t = - 1
smaller zero is t = - 3
larger zero is t = - 1
