Answer:
-9√11
Step-by-step explanation:
Simplify 5√11-12√11-2√11
Applying,
The law of surd,
Step 1: factor out the common surd or irrational number i.e √11
√11(5-12-2)
√11(-9)
Step 2: Multiplying the whole number and the surd
-9√11
Therefore,
5√11-12√11-2√11 = -9√11
Hence the right option from the list of option is
c -9√11
Answer:
36 mph
Step-by-step explanation:
d = rt
d = (x)(3.6)
d = (x-4)(4)
3.6x = 4x - 16
-0.4x = -16
x = 40
Her speed was 40 on Thursday, so 36 on Friday
Answer:
x = 
Step-by-step explanation:
Using Pythagorean Theorem we can say;
15² + x² = 18²
225 + x² = 324
x² = 99
x = 
To simplify this in the radical for we can say:



So the answer = 
Hope this helps!
Answer:
30 miles
Step-by-step explanation:
1/4 = 2
3 3/4 = x
15/4 = x
So, Cross multiply
=> 1/4 * x = 15/4 * 2
=> 1/4x = 15/4 * 4/2
=> 1/4x = 60/8
=> 1/4x = 7.5
=> 1/4x * 4 = 7.5 * 4
=> x = 30
So, 15/4 inches on the map equals 30 miles.
