when is 9 = 15.2 - 0.537x
9 = 15.2 - 0.537x
-15.2 -15.2 subtract 15.2 from both sides
-6.2 = -0.537x
/-0.537 /-0.537 divide -0.537 from both sides
11.55 = x or 12 feet round to nearest whole foot
3m^2+2p^2-15
3(3)^2+2(10)^2-15
3(9)+2(100)-15
21+200-15

Answer:
A. Twice the radius, d = 2r
Step-by-step explanation:
The diameter is a line that splits a circle in half, while the radius is only half of that.
Hello!
First you have to find the surface area of what he is painting
Finding the areas of all the rectangles he is painting
14 * 8 = 112
14 * 8 = 112
12 * 8 = 96
12 * 8 = 96
12 * 14 = 168
Add all these up
112 + 112 + 96 + 96 + 168 = 584
Divide this by the amount of area a pint of paint covers
584 / 90 = 6.4888...
He needs 7 pints of paint because he needs more than 6
Multiply this by the cost of 1 pint of pint
7 * 7.98 = 55.86
The answer is $55.86
Hope this helps!
Step 1
Find the area of one equilateral triangle
Applying the law of sines
in this problem
a=b=7 cm
C=60 degrees
so
cm²
Step 2
To calculate the area of the hexagon multiply the area of one equilateral triangle by 
![Area Hexagon=6*[49*\frac{\sqrt{3}}{4}] \\ Area Hexagon=73.5*\sqrt{3}](https://tex.z-dn.net/?f=%20Area%20Hexagon%3D6%2A%5B49%2A%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B4%7D%5D%20%20%5C%5C%20Area%20Hexagon%3D73.5%2A%5Csqrt%7B3%7D%20%20)
cm²
therefore
the answer is the option
73.5 sqrt 3cm²
