The area of this irregular figure sq ft

Area = 140 sq. ft

Step-by-step explanation:

Divide the figure into two shapes: rectangle and triangle.

Solve the area of the triangle first:

A = 1/2 bh

A = 1/2 (6)(4)

A = 1/2 (24)

A = 12

Solve the area of rectangle:

A = lw

A = (8)(16)

A = 128

Area of figure = area of triangle + area of rectangle

Area of figure = 12 + 128

Area = 140 sq. ft

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
