Step-by-step explanation:
Let's call x the lenght and y the height. The perimeter will be:
p = 2x + 2y = 10
When the lenght is halved and the height double we'll have:
p = x + 4y = 14
These 2 equations form a system of equations2 that can be solved and give as result:
y = 3
x = 2
1 mile=5280 feet how about 52800
1 x 52800 divided by 5280=10 miles
The answer to this question is x^(rt + s) since (x^r)^t becomes x^(rt) by the exponent power of a power property. Then multiplying powers of the same base results in the exponents being summed.
68>6t+4 when ever the number is per something(the 6) you put the variable with it and 4 is the constant
t>16
