Monday=m
friday=f
wednsday=w
w=m-4
f=2w
w+m+f=26
In terms of w:
w+w+4+2w=26
w+w+2w+4=26
4w+4=26
4w=22
w=5.5
f=2w
f=5.5*2
f=11
Hope this helps :)
Answer:
b and c, b and c are same
Step-by-step explanation:
Only a and d can be evaluated using simple substitution.
For a, integral of the square root of (x-1)dx i.e
let y = x-1
dy = dx
It becomes integral square root of ydy, ∫√ydy
which is can easily be evaluated and y is substituted back.
For d, integral of x times the square root of the quantity x squared minus 1
let y= x squared minus 1
then dy = 2xdx
dx = dy/2x
It becomes integral x times square root of y dy/2x
∫x√ydy/2x=∫√ydy/2=1/2∫√ydy which can easily be evaluated and y is substituted back
Answer:
Step-by-step explanation:
the fourth option shows a list of the first 6 prime numbers
Answer:
B) 2(x+4)
C) 3(3x+5)−7x–7
Step-by-step explanation:
B) 2(x+4) = 2x + 8
C) 3(3x+5)-7x-7
= 9x +15 - 7x - 7
= 9x - 7x + 15 - 7
= 2x + 8
