Step-by-step explanation: Multiply k and 9
Multiply k and 1
The k just gets copied along.
The answer is k
k
9*k evaluates to 9k
Multiply m and 9k
Multiply the m and k
Multiply m and k
The m just gets copied along.
The k just gets copied along.
The answer is mk
mk
9*k*m evaluates to 9mk
Multiply u and 9mk
Multiply the u and mk
Multiply u and mk
The u just gets copied along.
The m just gets copied along.
The k just gets copied along.
The answer is umk
umk
9*k*m*u evaluates to 9umk
Multiply l and 9umk
Multiply the l and umk
Multiply l and umk
The l just gets copied along.
The u just gets copied along.
The m just gets copied along.
The k just gets copied along.
The answer is lumk
lumk
9*k*m*u*l evaluates to 9lumk
Multiply t and 9lumk
Multiply the t and lumk
Multiply t and lumk
T
It is d, you first have to see how many times 0.2 goes into 18
Coolio
lw=1000
lets assume that the aluminum sides are the legnth
2 sides
2*15=30
30l=cost of aluminum
steel=10w
wood=(w-10)5=5w-50
we can eliminate the w by solving for w in first relation
lw=1000
divide both sides by l
w=1000/l
sub that for w
10(1000/l)=steel
5(1000/l)-50=wood
wood cost+steel+aluminum cost=total cost
10(1000/l)+5(1000/l)-50+30l=1525
(10000/l)+(5000/l)-50+30l=1525
(15000/l)-50+30l=1525
add 50 to both sides
(15000/l)+30l=1575
times both sides by l
15000+30l²=1575l
minus 1575l from both sides
30l²-1575l+15000=0
factor
(15)(l-40)(2l-25)=0
set each equal to 0
l-40=0
l=40
2l-25=0
2l=25
l=12.5
the there are 2 possible combinations
aluminum=40yd and steel=25yd or
aluminum=12.5yd and steel=80ft
both yield 1000yd² and cost $1525
