Answer:
85
Step-by-step explanation:
Use the pythagorean theorem!
(think that is how you spell it )
Pythagorean theorem: a² + b² = c²
a and b are the numbers that you have in this example, c is the side you need!
75² + 40² = c²
5,625 + 1,600 = c²
7,225 = c²
(the square root and square cancel each other out)
85 = c
c = 85
2(x+1)=2x+2
^^^^^^2 gets distributed to both sides in the brackets.
the answer comes out to 2x+2.
therefore, 2x+2=2x+2.
If the temperature is the same in Farenheit and Celsius, the variable F is equal to the variable C in the equation. Thus, you'll just need to replace one or both variables in the original equation and solve for the single variable. I'll just use x as the variable here:
F = 1.8C + 32
x = 1.8x + 32
subtract x from both sides
0 = 0.8x + 32
subtract 32 from both sides
-32 = 0.8x
divide both sides by 0.8
-40 = x
So, since we know x = -40 degrees, we also know that F = -40° and C = -40° too.
Answer:
X ints = (-1,0) , (3,0)
Y int = (0, -3)
Minimum (as it infinitely extends positively, but does not go down all the way)
Min point = (1,-4)

Answer:
5 inches by 
inches
Step-by-step explanation:
According to the scale given, to convert "feet" to "inches", we have to multiply each feet by 1/4th. The drawing would be a "smaller" version of the original. That would be in inches.
So, 20 ft would be:
20 * 1/4 = 20/4 = 5 inches
and
27 feet would be:
27 * 1/4 = 27/4 inches
The dimension would thus be:
5 inches by inches
