Area=l*b=l*(l-2)=80(given)

so, l^2 - 2l =80
l^2 - 2l - 80=0
l=10 or -8

l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36

8 of width, 10 of length, now 2(8) + 2(10)= 36 Inches

Answer:

Step-by-step explanation:

Z = (x-µ)/(s/√n)=(98.5-98.2)/(0.62/√19) = 2.11

left tail p-value = 0.9826

so 98.26% are lower.

Help Me!!!

Zigmanuir [339]

I'll just help quickly with a couple of expressions that are equivalent.
3(m+5+9m)
If you solve it out, you get 3m+15+27m.
Simply the expression to get 30m+15.
You can regroup to make another expression 5(6m+3) which is also equal.

Dan borrow s money to buy a new trumpet $400 at a simple interest rate of 5% he writes the equation t=400 +(0.5×400) to represen

kvasek [131]

<h3>Dan's equation is wrong.</h3>

Step-by-step explanation:

Given, Dan borrows money to buy a new trumpet $400 at simple interest rate of 5% .

${\textrm {simple interest} = \frac{P \times r \times t}{100}$ here P =$400, r = 5% and t = 1

$=\$\frac{400 \times 5 \times 1}{100}$

$=\$(0.05\times 400)$

Therefore he will need to pay back after one year is = 400+(0.05×400)

So, t = 400+(0.05×400)

Dan's equation is wrong.

Find the greatest common factor of 65a3b4 and 39a4b5.

natima [27]

Step-by-step explanation: Let's begin by finding the

greatest common factor for the numbers 65 and 39.

I would make a factor tree and break up 65 and 39.

So 65 is 13 x 5 and 39 is 13 x 3.

Since the 13's match up, the greatest

common factor between 65 and 39 is 13.

For the variables, we use the smallest power on each of them.

So we use a^3 and b^4 to get 13a^3b^4 as our GCF.
