Answer:
5 -2√10 = C
Step-by-step explanation:
√25 -√40
√25 = √5 x5 = √5² = 5
√40 = √5 x 8 = √5x 2x4 = √10x4 = √10x 2² = 2√10 (when the 2 comes back into the square root it become 2²)
√25 -√40 = 5 -2√10

Answer:
Length of the base is 16 yards.
Step-by-step explanation:
We are given that,
Area of the triangle = 80 yd²
Height of the triangle = 10 yards
Since, we know,
Area of a triangle = 
So, we get,

i.e. 
i.e. 
i.e. Base = 16 yards
Thus, the length of the base is 16 yards.
Answer: 15/24 + 6/24 = 21/24
Step-by-step explanation
when you put the new denominator (which is 28 on both fractions) you have to multiply the numerator by how many times it takes the denominator. example. 5/8 8 can go into 24, 3 times so u multiply
5 by 3 same with the other side just u multiply 3 by 2
