Generally, x <span>• x is accepted to mean "x times x" or "x multiplied by x"
and x+x means "x plus x" or "x added to x"
let's try by subsituting numbers for them
if we can find one case where the statement "x+x is the same as x</span><span>•x" is false, then it is not true
let's try x=4
x+x=x</span><span>•x
4+4=4</span>•<span>4
8=16
false
so it is not true
(x+x is equal to 2x, so therefor if we were to solve 2x=x</span><span>•x, we would get that it is only true for x=2 and x=0)
it is not always true

Answer: y = 18/32
Step-by-step explanation: Okay the equation is xy = k
You plug in x and y.
(3)(6) = k
18 = k
To get the value of y when x = 32 you plug in 32.
Use this equation now y = k/x
Now it is y = 18/32
And that is your answer!
Answer:
This is the answer I got
Step-by-step explanation:
JK / KL = MN / NP 6 / 4 = 18 / 12
Now u cross multiply. if both numbers are equal, they are similar. In this case, they are similar. 6 x 12 = 4 x 18
72 = 72
though the two corresponding sides of the triangles mentioned are proportional (proportionality being 1:3 ) but they need not be similar
for similarity either the third corresponding sides must be proportional or the included angle between the two proportional sides must be equal
Answer:
2,600,000
Step-by-step explanation:
To determine the number of license plate that can be made with one letter and 5 digits;
Number of English alphabet = 26
Number of digits from 0 to 9 = 10
Each letter have 26 possible options and each digit have 10 possible options.
Number of license plate that can be made is;
N = 26 × 10^5
N = 2600000
1/2 hour = 105 miles
Divide by 1/2 on both sides :
1/4 hour = 52.5 miles
