1. find the area of the two triangles, including the shaded section. the formula for this is a=1/2bh
the height and base are both 24 inches. this is because you add the 10 from the side of the square to the 14 that is given
so:
a=1/2(24)(24)
a=(12)(24)
a=288 sq. inches
since there are two triangles, you would multiply the area by 2
a=2(288)
a=576 sq. inches
now, since you only need the unshaded section, you have to take away the shaded section, which is a square. to do this, you must calculate the area of the square and take it away from the area of both triangles.
a=576-(lw)
a=576- (10)(10)
a=576-100
a=476 sq. inches
that is your answer

Answer:
Option c, d and e are equivalent expressions to 7x-14
Step-by-step explanation:
Which expressions are equivalent to 7x - 14
Equivalent Expressions:
<em>The expressions that are the same, even if the expression looks different.</em>
<em>For example: 2x^2+4 is equivalent to 2(x^2+2) because solving 2(x^2+2) we get 2x^2+4</em>
Now, finding equivalent to expressions 7x - 14
Option a) 14 - 7x
Not equivalent to 7x-14
Option b) x-2
Not equivalent to 7x-14
Option c) -(14 – 7x)
Simplifying: -14+7x so, equivalent to 7x-14
Option d) (x - 2)
Simplifying: 7x-14 so, equivalent to 7x-14
Option e) - 14 + 4x
Simplifying: 3x+4x-14 = 7x-14, so, equivalent to 7x-14
Option f) 2x - 10 + 5x + 4
Simplifying: 2x+5x-10+4 = 7x-6 so, Not equivalent to 7x-14
So, Option c, d and e are equivalent expressions to 7x-14
circumference of a circle (C)
C = πd or 2πr ( because d 2 x r)
r= 18 miles given
d= diameter
r= radius
d = 2 x r
d = 2 x 18 = 36 miles
2) C = πd
C = 3.14 x 36 = 113.04 miles
3) approximate measure of C = 22/7 x 36= 113.14 miles
