A=LW, and we are told that L=W+10
Using L=W+10 in A=LW you have:
A=(W+10)W
A=W^2+10W
W^2+10W=880, we are told that A=880 so
W^2+10W=880 now we can complete the square...
W^2+10W+25=905
(W+5)^2=905
W+5=±√905
W=-5±√905, since W>0
W=-5+√905 and since L=W+10
L=5+√905
W=-5+√905 ft and L=5+√905 ft
If we want an approximation:
W≈25.08 ft and L≈35.08 ft (both dimensions to the nearest hundredth)
Answer:
f(-3) = 4(-3) + 5 = -12 + 5 = -7. the answer is #2.
The percent is 5% cause
25+85=105
105-100= 5%
Answer:
B
Step-by-step explanation:
there is a common difference between consecutive terms in the sequence, that is
20 - 4 = 36 - 20 = 52 - 36 = 16
thus to obtain the next term in the sequence add 16 to the previous term
To obtain 2 terms distant then add 16 + 16 = 32
so 6th term = 52 + 32 = 84
