Answer:
Surface area of square pyramid = 
Step-by-step explanation:
Let, b is the base edges and s is the slant height
According to given condition:
b = 5 cm
s = 3 cm
Find out:
Surface area of square pyramid = ?
Formula:
Surface area of square pyramid = 
Solution:
Surface area of square pyramid =
Surface area of square pyramid = 
Surface area of square pyramid = 
Surface area of square pyramid =
-2(1-7n)-5n=34
Multiply the bracket by -2
(-2)(1)=-2
(-2)(-7n)=14n
-2+14n-5n=34
-2+9n=34
Move -2 to the other side. Sign changes from -2 to +2.
-2+2+9n=34+2
9n=34+2
9n=36
Divide by 9 for both sides
9n/9=36/9
n=4
Answer: n=4
Answer:
10 quarters
x=10
Step-by-step explanation:
25 pennies equals to .25 ⊄
6 nickels equals to .30⊄
2 dimes equals to .20⊄
Add it up: 25+30+20=75⊄
You will then subtract .75 from our total:
3.25-.75=2.50
You need 2.50 in quarters; remember .50 for two quarters and 1.00 for four.
Eight quarters will equal 2.00
and two quarters equals 50.
Add it up, 10 for 2.50.
You will have 10 quarters.
X=10
