Answer:
m<XDQ = 41 °
m<UXD = 139 °
Step-by-step explanation:
To find the area the easyiest divide it into 2 shapes that we know the area formula for: a triangle and a rectangle
the rectangle is 5 units by 7 units
A=l*w
A=5*7
A=35
the triangle is 4 units at the base and 5 units in height
A=bh/2
A=(4)(5)/2
A=20/2
A=10
To get the total area add the 2 areas together
35+10=45
Answer: Area of the yellow shape is 45 sq units
Answer: C
Step-by-step explanation:
C beacause one X cannot have two different Y values
All are 60 degrees because of equal lengths and equal angles
Since 180 ° in triangle means 180/3 =60
Hope this helps!
Answer:
A sqrt(x+2) - sqrt(x)
Step-by-step explanation:
2
--------------
sqrt(x) + sqrt(x+2)
Multiply top and bottom by sqrt(x) - sqrt(x+2)
2 sqrt(x) - sqrt(x+2)
------------------------ * --------------------------
sqrt(x) + sqrt(x+2) sqrt(x) - sqrt(x+2)
FOIL the denominator
2 (sqrt(x) - sqrt(x+2))
------------------------------
sqrt(x^2) - sqrt(x) sqrt(x+2) + sqrt(x) sqrt(x+2) - sqrt(x+2)^2
2 sqrt(x) - 2 sqrt(x+2)
------------------------------
x - (x+2)
Distribute the minus sign
2 (sqrt(x) - sqrt(x+2))
------------------------------
x - x-2
2 (sqrt(x) - sqrt(x+2))
------------------------------
-2
Cancel the 2 in the top and bottom
(sqrt(x) - sqrt(x+2))
------------------------------
-1
Distribute the -1
sqrt(x+2) - sqrt(x)
