Answer:

P = 2(l+w)\\Length = 5x\\Width = 3x+7\\\\P = 2(5x +(3x+7))

Step-by-step explanation:

Further Solving :

P = 2(5x +(3x+7))\\P = 2(5x+3x+7)\\P = 2(8x+7)\\\\Perimeter = 16x + 14

what is an equation of the line that is perpendicular to y + 1 = -3(x-5) and passes through the point (4, 6)
Korolek [52]

\text{Let}\ k:y=m_1x+b_1\ \text{and}\ l:y=m_2x+b_2,\ \text{then}\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\l\ \parallel\ k\iff m_1=m_2\\\\\text{We have}\ y+1=-3(x-5)\to m_1=-3.\\\\\text{Therefore}\ m_2=-\dfrac{1}{-3}=\dfrac{1}{3}.\\\\\text{The point-slope form:}\ y-y_1=m(x-x_1).\\\\\text{Put the value of slope and the coordinates of the point (4, 6) to the equation}:\\\\\boxed{y-6=\dfrac{1}{3}(x-4)}

Principal = 5 3 0 0 =5300equals, 5300 rupees Annual rate of interest = 6 . 5 % =6.5%equals, 6, point, 5, percent Total amount =
creativ13 [48]

The formula is

A=p (1+r)^t

A future value 6678

P present value 5300

R interest rate 0.065

T time?

6678=5300 (1+0.065)^t

6678/5300=(1+0.065)^t

Take the log for both sides

Log (6678/5300)=t×log (1+0.065)

Divide both sides by log (1+0.065)

T=(log(6,678÷5,300)÷log(1+0.065))

T=3.7 years


Hope it helps!

How can you check the reasonableness of your solution
storchak [24]

You would basically go back and trace all your steps, that's what I do. And if your answer seems reasonable then you have the right answer but if your work doesn't match the answer than you've messed up.   I hope I helped if I did like my answer and comment down below thx
