A=12in²
Step-by-step explanation:
b Base 8in
hb Height 3in
A=hbb
2=3·8
2=12in²
Answer:
8
Step-by-step explanation:
6t - 20 - 32u = ?
t = 6 u = 1/4 [.25]
6*(6) - 20 - 32*(1/4)
36 - 20 - 8 = ?
? = 8

it would mean a lot if you marked as brainliest :)
Answer:
4.5 cm^2
Step-by-step explanation:
Area of trapezoid = ((base 1 + base 2) / 2) * height
According to the figure:
base 1 = 1.1 cm
base 2 = 3.4 cm
height = 2 cm
Now plugin into formula:
A = ((b1 + b2 ) / 2) * h
A = ((1.1 + 3.4) /2) * 2
A = ( 4.5/2 ) * 2
A = 2.5cm * 2cm
A = 4.5 cm^2

Answer:
a₁ = 37
Step-by-step explanation:
In an arithmetic progression the common difference d is
d = a₂ - a₁ = a₃ - a₂ , that is
2x - 18 - (x + 1) = 2x - 1 - (2x - 18) ← distribute and simplify both sides
2x - 18 - x - 1 = 2x - 1 - 2x + 18
x - 19 = 17 ( add 19 to both sides )
x = 36
Thus
a₁ = x + 1 = 36 + 1 = 37
13a. The figure has 5 sides and 5 vertices.
13b. None of the sides are congruent, so the figure is not a regular polygon.
13a. The sides are the straight lines and vertices are the points.
13b. It is not regular because regular polygons have congruent sides.
