X= width of the path.
we can suggest this equation:
(20+2x)(28+2x)=1584
we solve this equation:
(20+2x)(28+2x)=1584
560+40x+56x+4x²=1584
4x²+96x-1024=0
4/4x²+96/4x-1024/4=0/4
x²+24x-256=0
We solve this square equation:
x=[-24⁺₋√(576+1024)]/2=(-24⁺₋40)/2
we have two solutions:
x₁=(-24-40)/2=-32 this solution is not valid.
x₂=(-24+40)/2=8
Answer: the width of the path is 8 m.
Answer:you need common denominatord 4*2=8 3*2=6 6/8+1/8=7/8 of sugar
Step-by-step explanation:
Answer: x=-1/6y+-11/3, y=-6x-22
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Note the following 3 points with respect to a function given as y = f(x).
1. The function y = f(-x) is a reflection across the y-axis
2. The function y = f(x+a) is a horizontal translation a units left and y = f(x-a) is a horizontal translation a units right
3. the function y = f(x) + a is a vertical translation a units up and y = f(x) - a is a vertical translation a units down
Dissecting the transformed function of f(x) = ln (3-x) -2 w.r.t f(x) = ln x, we see:
<em>1. x is replaced with -x, so </em><u><em>reflection across y-axis</em></u>
<em>2. we have a horizontal shift in left side because the argument of ln is (3-x) or (-x+3)</em>
<em>3. We have vertical shift 2 units down because there is a -2 after the functional part of ln(3-x)</em>

Looking at the choices, A is the right answer.
Answer:
d. 2/9
Step-by-step explanation:
7/8 - 0.85
3/5 - 0.6
5/2 - 2.5
2/9 - 0.222... the two is a recurring number
