Answer:
<h2>64 cm²</h2><h2 />
Step-by-step explanation:
surface area of a square base pyramid = base area + 4 ( triangular sides area)
where:
base = 4 cm
side height length = 6 cm
Surface area = 4² + 2(4)6
= 16+ 48
= 64 cm²

Step-by-step explanation:
It will be b after you do the math
Answer:
50
Step-by-step explanation:
Sum Even numbers
n = 50
d = 2
a1 = 2
The last number is
an = a1 + (n-1)d
an = 2 + (50 - 1)*2
an = 2 + 49 * 2
an = 2 + 98
an = 100
Sum of the even numbers
Sum = (a1 + a50)*n/ 2
Sum = (2 + 100)*50/2
sum = 102 * 25
sum = 2550
Sum of the first 50 odd numbers
a1 = 1
n = 50
d = 2
l = ?
Find l
l = a1 + (n - 1)*2
l = 1 + 49*2
l = 99
Sum
Sum = (1 + 99)*50/2
Sum = 2500
The difference and answer is 2550 - 2500 = 50
