Let h be the height of the triangle. With this the base may be represented as 7h - 2. The area of the triangle is half the product of its base and height. Therefore,
A = (1/2)bh = (1/2)(7h - 2)h
Substitute to the equation the value of h,
A = (1/2)((7)(14 cm) - 2)(14 cm)
A = 672 cm²

Answer:
<h2>b > - 5/1</h2>
Step-by-step explanation:
The statement
Twice the difference of a number and 8 is written as
2( b - 8)
The expression is greater than - 21 so we represent it by the > sign
So we have
2( b - 8) > - 21
Expand
2b - 16 > - 21
2b > - 21 + 16
2b > - 5
Divide both sides by 2
<h3>b > - 5/2</h3>
Hope this helps you
