Answer:
Total surface area of cube = 294 cm²
Step-by-step explanation:
Given:
Perimeter of cube = 84 cm
Find:
Total surface area of cube
Computation:
Perimeter of cube = 12 x side
84 = 12 x side
Side = 7 cm
Total surface area of cube = 6(a)²
Total surface area of cube = 6(7)²
Total surface area of cube = 294 cm²
Factor it out first so:
y=(x+13)(x-2)
Then you know that x= -13 and 2 to make the equation 0

Answer:
1. adjacent angles
2. supplementary angles
3. Angle G = 144 Angle H = 36
4. 45 degrees
Step-by-step explanation:
For #3, u can make an equation to help solve:
4x + x = 180
5x = 180
x = 36
For #4, since complementary angles = 90, u can subtract 45 from 90 to get ur answer.
90 - 45 = 45
hope this helps!!
