Answer:
x = 63.9
Step-by-step explanation:
We have:
= 
=> QR × sin90 = 78 × sin35
=> QR × sin90 = 44.7
=> QR = 44.7
But, we also have: 
+ 
= 
<=> + 
= <=> = 6084 - 1998.09
=> = 4085.91
=> x = 
= 63.9211.. = 63.9
<3 Have a nice day!!
Answer:
A
Step-by-step explanation:
Let the smaller room have an area of x^2
Let the larger room have an area of (x + 3)^2
(x+3) ^2 + x^2 = 89 Be careful not to make it 89^2.
x^2 + 6x + 9 + x^2 = 89 Expand the binomial squared
2x^2 + 6x + 9 - 89 = 0 Subtract 89 from both sides
2x^2 + 6x + 9 - 89 = 0 Combine
2x^2 + 6x - 90=0 Divide by 2
x^2 + 3x - 45 = 0 This factors.
(x + 9)(x- 5) = 0
X + 9 gives nothing useful
x - 5 = 0
x = 5
x + 3 = 5+3 = 8
So the answer is A
Answer:
-3/4
Step-by-step explanation:
Option 1
Direction of the line: Down
-Negative Slope
Rise=-3
Run=4
Rise/Run=-3/4
Option 2
Points: (1,-2) and (-3,1)
y2-y1/x2-x1= 1-(-2)/-3-1
1+2/-3-1
-3/4
Answer:
3/4 of a hour
Step-by-step explanation:
2 miles = 0.5 hours
Divide by 2
1 mile = 0.25 hours
