Step-by-step explanation:
60% = 18 +
20% = 6 ( cos its 1/3)+
20% = 6 =
100% = 30
Answer:
Step-by-step explanation:
p² + 14p + 49 = p² + 2 * 7p + 7²
Comparing with a² + 2ab + b²,
a= p and b = 7
So 2ab = 2*p*7 = 14 p
So, p² + 14p + 49 is a perfect trinomial
1. width=7
2. 7 x 3 = 21
3. length= 21
4. 21 x 7= 147 sq ft
5. length x width = --- sq ft
is this confusing?
hope it helps!
