The area of the trapezoid is 43.5 inches²
Step-by-step explanation:
The formula of the area of a trapezoid is 
, where:
and 
are the two parallel bases- h is its height
∵ = 
feet
∵ = 14 inches
∵ h = 3 inches
- Change the length of from feet to inches
∵ 1 foot = 12 inches
∴ feet = × 12 = 15 inches
∴ = 15 inches
Substitute the values of , and h in the
formula of the area
∴ 
∴ A = 43.5 inches²
The area of the trapezoid is 43.5 inches²

Answer:
Solve
Step-by-step explanation:
To find the surface area of a triangular prism, use the formula Surface Area = L + 2B, where L is the lateral area and B is the area of the base. Find the lateral area by calculating the perimeter of the base and multiply it by the height of the prism.
X=-2/5
Steps:
6^x/3 +2 = 6^-14x/3
x/3+2 = -14x/3.
x +6 = -14x (multiply both sides by 3)
x = -14x - 6 (Substract 6 from both sides)
x + 14x = -6 (add 14x to both sides)
15x = -6 (collect like terms)
x = -2/5 (divide both sides by 15)
<span>In
the given situation, a jewelry maker has the following:
=> 24 jade beads
=> 30 teak beads
Now, how many necklace can a jewelry maker make with this number of beads.
=> 24 + 30 = 54
=> (8 x 3) + (10 x 3) = 54
=> (8 + 10) x 3 = 54
=> 18 x 3 = 54
=> 54 = 54
Thus, the number of necklace is 3 with 8 jade and 10 teak beads in it.
