PEMDAS!!! (Parentheses, exponents, multiplication, division, addition, subtraction)
Step-by-step explanation:
Parentheses first!
50-35=15
Then subtraction!
80-15=65
Hope this helped!!! :)
Answer:
A) length = width +10
B) length * width = 144 OR
B) width = 144 /length putting B) into A)
A) length = 144 / length + 10 then solving for length
A) length^2 = 144 +10 length
A) length^2 -10 length - 144 = 0 then we factor
(length -18) * (length +8) = 0
length = 18 feet
width = 8 feet

Answer:
<h2>on the positive y-axis</h2>
Step-by-step explanation:
Look at the picture.
(1) If x = 0, then the point is on the y-axis.
(2) If y > 0, then the point is above the x-axis.
From (1) and (2) we have: The point is on the positive y-axis.
Answer:
4
Step-by-step explanation:
Equating the y-values gives an equation in x.
4x -10 = (x -2)^2 +2
0 = x^2 -4x +4 +2 -4x +10 . . . . . . . . eliminate parentheses, subtract 4x-10
x^2 -8x +16 = 0
(x -4)^2 = 0
x = 4
The x-coordinate of the one point of intersection is x = 4.
