Answer:
24s^2, 54s^2, 96s^2
Step-by-step explanation:
Let s represent the initial side length of the cube. Then the area of each face of the cube is A = 6s^2 (recalling that the area of a square of side length s is s^2).
a) Now suppose we double the side length. The total area of the 6 faces of the cube will now be A = 6(2s)^2, or 24s^2 (a 24 times larger surface area),
b) tripled: A = 6(3s)^2 = 54x^2
c) quadrupled? A = 6(4s)^2 = 96s^2
For number 7 it’s basically 4x3 and 4x6 and for number 8 it’s 4x7 and 2x7
For number 9 it’s 5x3, 5x6, 5x2
They’re all adding 5, so 18+5=23
So I think 23
The answer is X=-1 because they crossed at -1
Step-by-step explanation:
Given:
Complementary angle = 68'
Angle measure = 90' - 68' = 22'
Supplementary angle = 180' - 22' = 158'
Angle classification = Acute angle
Given:
Supplementary angle = 161'
Angle measure = 180' - 161' = 19'
Complementary angle = 90' - 19' = 71'
Angle classification = Acute angle
Given:
Angle measure = 136'
Angle classification = Obtuse angle
Complementary angle = 136' - 90' = 46'
Supplementary angle = 180' - 136' = 44'
