Katie is five times older than Salma. Their total age is 18 years. In x years time Salma will be half Katie’s age. A) work out the value of x
B)work out the age of salma and Katie in x years time.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

45

step-by-step explanation:

answer: -0.5 would be the most likley outcome

step-by-step explanation:

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
