Answer:

98 ft

Step-by-step explanation:

2 (10ft x 4ft) + 6ft x 3ft = 98 ft

To find the area of the larger shape you need to break this into 3 rectangles. The first two (top and bottom) are the largest so let’s start there. They measure at 10ft across and 4ft down. 2 rectangles at 10ft x 4ft = 80ft or

2(10ft x 4ft) = 80ft

The last rectangle we can figure out by subtracting 7ft from 10ft across. This tells us that the smaller rectangle is 3ft across. We are given that the smaller rectangle is 6ft down. So we have 3ft x 6ft = 18ft

80ft + 18ft = 98ft

What is 2x + 4x + 4 = 4(x + 4) and step by step and Highlight / circle the error
mario62 [17]

Answer:

x = 6 and the +4x is wrong

Step-by-step explanation:

2x + 4x + 4 = 4(x + 4)

6x + 4 = 4x + 16

+4x +4x  <--( <u>This part is wrong</u> )

10x + 4 = 16

-4 -4

10x = 12

10 10

x = 1.2

Correct steps

2x + 4x + 4 = 4(x + 4)

6x + 4 = 4x + 16

-4x        -4x

2x + 4  = 16

      -4     -4

2x = 12

2       2

x = 6
