Answer:
English please?
Step-by-step explanation:
...........
30 x 30 = 900 too low
40 x 40 =1600 too high - so the answer lies somewhere between
30 x 31 (too low) 39 x 40 = too high
31 and 37 are the only primes between those numbers and that is her pin 3137
5+2w=l
2w+2l=130
2w+2(5+2w)=130
2w+10+4w=130
6w=130-10
w=120/6=20
l=5+2•20=45
Area=20•45= 900inches^2
Answer:
k = 0
Step-by-step explanation:
Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 6 from both sides
k² + 6 (-6) = 6 (-6)
k² = 0
Isolate the k. Root both sides
√(k²) = √(0)
k = 0
0 is your answer for k
