SOLVE THIS: 6(2x+3) =42
AlladinOne [14]

Answer:

x = 2

Step-by-step explanation:

First, distribute 6 to all terms within the parenthesis.

6(2x + 3) = 12x + 18

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

12x + 18 = 42

First, subtract 18 from both sides.

12x + 18 (-18) = 42 (-18)

12x = 24

Isolate the variable x. Divide 12 from both sides.

(12x)/12 = (24)/12

x = 24/12

x = 2

2 is your answer for x.

An isosceles trapezoid has base angles of 45° and bases of lengths 9 and 15. The area of the trapezoid is 36 sq. units 72 sq. un
Butoxors [25]

Answer:

Area = 36 sq units

Step-by-step explanation:

An isosceles trapezoid have two triangles and probably a rectangle or a square.

To find the area, let's determine the height of the trapezoid.

The base length of one of the triangle

= (15-9))2

= 6/2 = 3

The height will be x

X /sin 45= 3 / sin 45

X= 3

The area of the trapezoid

= 1/2(a+b)h

Where a = 15

b = 9

h = 3

Area= 1/2(15+9)3

Area= 1/2 *24*3

Area= 12*3

Area = 36 sq units
