First, you would solve the parentheses.
72-(7+8)*4
72-(15)*4
Then, you would do multiplication.
72-60=
12
Hope this helps!
Slope is the change in Y over the change in. X
Using two of the given points:
Slope = 70-45 / 25-10
Slope= 25/ 15
Slope = 5/3
Answer:
2^3 or 5^5
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer:
(1/8) ( 7 + sqrt(481) )
(1/8) ( 7 - sqrt(481) )
Discussion:
The equation is equivalent to 4x^2 - 7x -27 = 0 (as 3 + 24 = 0), Using the quadratic formula:
x = ( - (-7) +\- sqrt ((-7)^2- 4*4*(-27)) )/ (2*4)
= (1/8) ( 7 +\- sqrt(49+ 432) ) =
= (1/8) ( 7 +\- sqrt(481))

Since the scale is 1:30, that means 1 unit in the scale is equal to 30 units of the actual dimension. Multiply the number by 30 to get the actual dimension
