The perimeter of a rectangular garden is 254 feet. If the width of the garden is 51 feet, what is its length?

Answers

The length of the garden is 76 feet.
If the perimeter is 254 and the width of the garden is 51 feet, you must multiply the width by 2 (102) and than subtract that from the total perimeter (254 - 102 = 152) than divide the leftover amout by 2 (152 /2 = 76) making the length of the garden 76 feet long.

Answer:

$a^(n)$ (1 + a + a²)

Step-by-step explanation:

consider the rule of exponents

$a^(m)$ × $a^(n)$ = $a^((m+n))$

given $a^(n)$ + $a^(n+1)$ + $a^(n+2)$

Take out the common factor $a^(n)$

= $a^(n)$ (1 + a + a²)

How do I solve this problem 7 2/3 + n = 9 1/12

Answers

7 2/3+n=9 1/12
3•4=12
2•4=8
7 8/12+n = 9 1/12( these fractions have common denominators)
switch the operation (+ to -) and get the fraction by themselves
8/12-1/12=7/12
now subtract the whole numbers
9-7=2
finally answer 2 7/12
