formula for a diagonal line in a square is D = Square root of 2 times the length of the side
so square root of 2 times 300 = about 424 feet. the answer is the last one
c + 9 - 3(c - 10) > 1
We're going to treat this like a regular algebraic equation, thus most algebraic rules and properties apply.
First, apply distributive property.
c + 9 <u>- 3c + 30</u> > 1 (two - signs cancel out, creating a + sign.)
Combine like terms.
<u>-2c + 39</u> > 1
Subtract 39 from both sides.
-2c > <u>-38</u>
Divide both sides by -2.
<u>c < 19</u> (Because we're dividing by a negative number, the sign gets swapped.)
<h3>Your answer is c < 19.</h3>
Since:
Area of a triangle = 1/2 * base * height
2x^2 ∗ 3xy/2
<span>6x^3y/2 <span>= 3x^3y/1
3x^3y/1
Therefore, the </span></span>expression that represents the area of the triangle is <span>3x^3y/1.

a. Solution:
5y-3+3=-18+3
5y=-15
y=-15/5
y=3
b. Solution:
-3x-9+9=0+9
-3x=9
x=9/-3
x=-3
c. Solution:
4+3-3(z-8-3)=-23-3
4(z-5)=-20
4z-20=-20
4z-20+20=-20+20

z=4
d. Solution:
1-2+2(y-4+2)=5+2
3(y-2)=7
3y-6=7
3y-6+6=7+6
3y=13
y=13/3
y=4.33
Answer:
the height of the building is approximately 134 yards
Step-by-step explanation:
Recall that i order to use the arc-length formula:
we know the radius R, but the angle 
must be given in radians. Then we convert 
to radians, and then use 1700 yards as the radius in the formula.
Therefore, the arc length formula would render:
which rounded to the nearest yard becomes: 134 yards
