(4,-7)
Step-by-step explanation:
Answer:
Option A (2197 cm³)
Step-by-step explanation:
For a cube with length of each side "a" , it's
- Total Surface Area = 6a²
- Volume = a³
_____________________________________________
According to the question ,
Total Surface Area = 1014 cm²
Let the length of each side of cube be 'a'.
Using the formula ,



But length can't be negative . So , length of each side = 13 cm
∴ Volume of cube = 13³ = 2197 cm³
The first term a = 1,
Common difference, d: 7 - 1 = 6.
a(n) = a + (n -1)d,
For 30th term. = 1 + (30 -1)*6
= 1 + 29*6 = 1 + 174 = 175
Answer:
the answer is D
Step-by-step explanation:
5x+6=16
-6 -6
5x=10
divide both sides by five
x=2
Answer:
=4xy−4y2+16x−16y
Step-by-step explanation:
(2x−2y)(2y+8)
=(2x+−2y)(2y+8)
=(2x)(2y)+(2x)(8)+(−2y)(2y)+(−2y)(8)
=4xy+16x−4y2−16y
=4xy−4y2+16x−16y
