Cindy used 17.25 because 15 × .5 = 2.25 and if you add it to 15 ypu get 17.25
Answer:
<h2>
y = 3.5x + 15</h2>
Step-by-step explanation:
Number of months is x, and number of pairs of shoes after each month is y.
7 new pairs of shoes every 2 months means that after each month:
y = 7/2 x
We need to add the 15 pairs from start.
y = 3.5x + 15
4 cm x 4 cm would make a 16 cm area
just multiply 4 and 4 together to get the answer!
16 cm area
please mark the brainliest!
2D-a^2=2
2(a√2) -a^2=2
a^2-2√2*a+2=0
2a= 2√2 + √(8-4*2) = 2√2
hence, perimeter = 4a = 2*2a=2*2√2 = 4√2
