Answer:

210cm2

Step-by-step explanation:

Area of rectangle: HxW

Area of Triangle: 1/2 x bx h

There are 3 rectangles with the length of 14x3

14x3x3

= 14x9

= 126cm2

There are two triangles with the height of 12 and base of 14.

1/2x 14x 12

= 1/2x 168

= 168/2

= 84cm2

Now finally add them together:

84+126

= 210cm2

. Which of the following is equivalent to 7 - 2(x + 2) < -4 - 3(1 - x)?

andre [41]

Step-by-step explanation:

$7 - 2(x + 2) < -4 - 3(1 - x)$

First, let's distribute the terms outside each parentheses to get rid of them:

$7 - 2x - 4 < -4 - 3 + 3x$

$-2x + 3 < -7 + 3x$

Next, let's move the terms with an $x$ variable to the left side of the equation, and everything else to the right side:

$-2x -3x < -7 - 3$

$-5x < -10$
