Zarrin [17]3 years ago
5 0

Answer:

35 ft^2

Step-by-step explanation:

Area of the first rectangle

A = 8 x 2 = 16 ft^2

area of the second rectangle

A = 5 x 2 = 10 ft^2

area of the square

A = 3^2 = 9 ft^2

total area

A = 16 + 10 + 9 = 35 ft^2

Answer:

x^{15}

Step-by-step explanation:

Distribute the ^3 on top

(27 x^{6} y^{-9})

distribute the ^ -9 on bottom, only to what is in the parenthesis

(27 x^{-9} y^{-9})

the 27's cross out, the y^{-9} 's cross out

x^{6}/ x^{-9} is left

move the  x^{-9} to the top of fraction to change its sign

x^{6} · x^{9} = x^{15}

Given the equation 5x − 4 = –2(3x + 2), solve for the variable. Explain each step and justify your process.
blagie [28]
A.
5x-4=-2(3x+2) \ \ \ \ \ \ \ \ \ |\hbox{expand the bracket} \\
5x-4=-2 \times 3x-2 \times 2 \\
5x-4=-6x-4 \ \ \ \ \ \ \ \ \ \ \ \ \ |\hbox{add 6x to both sides} \\
11x-4=-4 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\hbox{add 4 to both sides} \\
11x=0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\hbox{divide both sides by 11} \\
x=0

B.
3(2x-4)=5x-1 \\
6x-12=5x-1 \\
\boxed{11x-12=-1} \Leftarrow \hbox{the first mistake} \\
11x=11 \\
\boxed{x=11} \Leftarrow \hbox{the second mistake}

Megan's solution isn't correct.
The first mistake: she subtracted 5x from the right-hand side of the equation, but added 5x to the left-hand side.
The second mistake: she divided the right-hand side of the equation by 11, but didn't divide the left-hand side.

The correct solution:
3(2x-4)=5x-1 \ \ \ \ \ \ \ \ \ \ \ |\hbox{expand the bracket} \\
3 \times 2x+3 \times (-4)=5x-1 \\ 6x-12=5x-1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\hbox{subtract 5x from both sides} \\
x-12=-1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \  |\hbox{add 12 to both sides} \\
x=11
