Answer:
The answer is: 181.5 square centimeters.
Step-by-step explanation:
The cube has six faces, and each face is a square with sides of length 5.5, so the area of one of this faces is 
, adding the six faces, we get the answer: 
Answer:
Step-by-step explanation:
To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.
Ax+By=C
Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.
8x−3=y
Move y to the left side of the equation because it contains a variable.
8x−3−y=0
Move 3 to the right side of the equation because it does not contain a variable.
8x−y=3
Answer:
All angles in a triangle sum up to 180 degrees.
So, 63+71+x=180 degrees.
You add like terms: 134, and then add x.
134+x=180 degrees.
Minus x from both sides.
180-134=x.
What do you think x is?
Answer:
-3/5
Step-by-step explanation:
First represent this with numbers. Less means subtraction -, times means multiplication *, is means equals =.
And let's represent "a number" with x.
63 - 15x = 72
Solve for x. First subtract 63 from both sides.
-15x = 72-63
-15x = 9
x = -9/15 = <u>-3/5</u>
Answer:
Step-by-step explanation:
A = h(a+b)/2 for h
2A = h(a + b)
h(a+b) = 2A
h = 2A/(a+b)
