Answer:
Answer: x equals to 2 and -5
Step-by-step explanation:
» Factorise the equation quadratically:
<span>So we wan't to know hot to convert degrees Fahrenheit to degrees Celsius. Let's transform first from Celsius to Fahrenheit: 0 degrees Celsius is 32 degrees Fahrenhiet and 1.8 degrees Celsius is 1 degree Fahrenheit so: T(F)=1.8T(C) + 32. To transform from Celsius to Fahrenheit we need to invert the former equation: 1.8T(C)= T(F)-32. Now we divide the whole equation with 1.8 and we get: T(C)=(T(F) - 32)/1.8 and input our T(F)=41 F and we get: T(C) =(41-32)/1.8 and that is equal to: T(C)= 5 C. So the correct answer is B. 5 degrees C</span>
Answer:
r = 7.5
Step-by-step explanation:
Circle equation: 
Since we are already give <em>r²</em>, we simply just take the square root of 56.25, and we should get 7.5 as our final answer!
Answer:
4 ft by 12 ft
Step-by-step explanation:
x^2 +8x -48
Set this equal to 0 to solve for the values of x
x^2 +8x -48=0
What two values multiply to -48 and add to 8
12*-4 = -48
12+-4 = 8
(x+12) (x-4) = 0
Using the zero product property
x+12 = 0 x-4=0
x=-12 x=4
We cant have a negative length
x=4
The area is 48
48/4 = 12
The other dimension is 12
