√5 (10-4√2)
=10√5-4√10
The answer is D
7 is a prime number because it is only divisible by 1 and itself which is 7.
Answer:
Step-by-step explanation:
(-1/8)/(-1/3) = (-1/8)×(3/-1) = (-1)(3)/(8)(-1) = -3/-8 = 3/8
Answer:
A and D have whole grid squares that are the same size and aren't over lapping
C has overlapping grid squares making it hard to count
B can't be used to find area because some of the grid squares are different sizes
You still could use B because four of the smaller squares seems to be equivalent to one of the larger squares
Step-by-step explanation:
Answer:
a = b = 1
Step-by-step explanation:
The triangles are similar thus ratios of corresponding sides are equal, that is
= 
( cross- multiply )
10b = 10 ( divide both sides by 10 )
b = 1
and
= 
( cross- multiply )
10a = 10 ( divide both sides by 10 )
a = 1
Thus a = 1 and b = 1
