25,32,35,43,43
median = 35
Answer:
Option D.
Step-by-step explanation:
The given expression is (5r + 2)(3r minus 4)
Convert this expression into an algebraic expression.
(5r + 2)(3r - 4)
By distribution law,
= 5r(3r - 4) + 2(3r - 4)
= 15r² - 20r + 6r - 8
= 15r² - 14r - 8
Now convert the algebraic expression into the language form.
15r squared minus 14r minus 8
Therefore, option D is the answer.
Answer:
y = 7, x = 7
Step-by-step explanation:
11y + 13 = 90
11y = (90 - 13)
11y = 77
y = 7
2x + 6 = 20 (because 20 is half of 40)
2x = (20 - 6)
2x = 14
x=7
BD is a angle bisector and Angle bisector theorem says
ratio of other sides of the triangle formed by bisector is equal
BA/AD=BC/CD
lets say AD is x so DC will be 4-x
3/x=4.5/4-x
x=1.6
AD=1.6units
so DC=4-x=4-1.6= 2.4 units
