Answer:
2) x² - 10x + 25
Step-by-step explanation:
(x - 5)(x - 5) = x² - 5x -5x + 25
Combining like terms
x² - 10x + 25
The ratio would be written as 2:3 because there are 2 girls for every 3 boys
Answer:
y = 4x - 3
Step-by-step explanation:
The values in the x column increase by 1 each time.
The values in the y column increase by 4 each time.
Therefore, the slope of your equation should be 4.
The y-intercept is -3 when x = 0.
The final equation would be:
y = 4x - 3
Answer:
9.19
Step-by-step explanation:
Using Law of sines to find other two lengths:
a/sinA=b/sinB
let a be length of side unknown and b be hypotenuse then sinB=sin90 and sinA=sin45
a/sin45=13/sin90
a=13sin45
a=13(0.707)
=9.19
As the given triangle is isosceles hence the length of other two legs will be same i.e 9.19 !
