W - a width
3w - a length
27 ft² - an area
Therefore:
w · 3w = 27
3w² = 27 |:3
w² = 9 → w = √9 → w = 3
3w = 3 · 3 = 9
width = 3
length = 9
The perimeter:
P = 2 · width + 2 · length
P = 2 · 3 + 2 · 9 = 6 + 18 = 24 ft.
SOLVED = 75(-7)’+3.1-3
SOLUTION = 75-7’+3.1-3 = 75.1
we need the graph/ lines,
but just remember
wherever 2 lines intersect, that is a solution
if they are paralell, no solutions
if they cross, 1 solution
if they are the same line/ the lines are on top of each other exactly, infinite solutions
Bode paid on average $1200 × 11% = $132 each month in interest. If Bode made 12 mortgage payments last year, he paid
... 12 × $132 = $1584
in mortgage interest.
Let's get that answer!
Subtract 2 from both sides: 3y + 2 - 2 = 23 - 2
After Subtracting: 3y = 21
Divide both sides by 3: 3y/3 = 21/3
y = 7 is the answer
