Step-by-step explanation:
A=bh/2.
A=(21*8)/2
A=168/2
A=84
First make an equation for first tree
Y=2x+50
Then second tree
Y=1x+59
Then put them equal to eachother
2x+50=1x+59
Solve by subtracting 1x and then subtracting 50
Answer= x=9
9 months
I think it’s 40
The width is 8
And the length is 5
8 x 5 is 40
Let the numbers be a and b, then ab=0.2 and a/b=0.8, so a=0.8b. Therefore, 0.8b^2=0.2 and b^2=0.2/0.8=2/8=1/4 and b=+1/2 or +0.5 and a=+0.8*0.5=+<span>0.4. The two numbers are therefore 0.5 and 0.4 or -0.5 and -0.4. The quotient is 0.4/0.5</span>
6.12% compounded monthly equals 0.0612/12, or 0.0051 added monthly. So, $3500 invested for 4-1/2 years is:
3500 x (1.0051)^(48+6)=1.3161x3500=$4606.48
