Answer:
1350 mm²
Step-by-step explanation:
The area of each square face is the square of the edge length:
... face area = (15 mm)² = 225 mm²
There are 6 square faces on a cube, to the total surface area is 6 times that of one face:
... cube area = 6 × face area = 6×225 mm² = 1350 mm²
Answer:
36
Step-by-step explanation:
Given
m² - 2mn + n² , substitute values
= (- 2)² - 2(- 2)(4) + 4²
= 4 - 2(- 8) + 16
= 4 + 16 + 16
= 36

Answer:
The answer is A
Step-by-step explanation:
You should set "I" as
1 0 0
0 1 0
0 0 1
then replace "a" to 0.5 and "b" to 0.1
then finally you multiply matrice C and D
If your answer is
1 0 0
0 1 0
0 0 1
then the answer will be A
Y= -2x-5
Y=8x+5
^^ those two equations are basically the same so you put them side by side like:
-2x-5=8x+5
Subtract 5 on both sides which leads to:
-2x-10=8x
Add 2x both sides:
-10=10x
Divide both sides by 10
-1=x
