Answer:
The surface area would be 28 square feet.
Step-by-step explanation:
To solve this, input the values for each of the variables every time you see it. l = length, w = width and h = height.
SA = 2lw + 2hw + 2hl
SA = 2(2)(1) + 2(4)(1) + 2(4)(2)
SA = 4 + 8 + 16
SA = 28
Reflection across the y-axis
bc it's in the 3rd and it goes into the 4th. this is over the y-axis. in 3rd you coordinates would be (-,-) and in the 4th they would be (+,-) in which case they are in the final triangle
Answer:
Rational.
Step-by-step explanation:
It is rational because the digits did not go on forever.
Answer:
x = -4
Step-by-step explanation:
Solve for x:
3 x - 5 x + 2 = 10
Grouping like terms, 3 x - 5 x + 2 = 2 + (3 x - 5 x):
2 + (3 x - 5 x) = 10
3 x - 5 x = -2 x:
-2 x + 2 = 10
Subtract 2 from both sides:
(2 - 2) - 2 x = 10 - 2
2 - 2 = 0:
-2 x = 10 - 2
10 - 2 = 8:
-2 x = 8
Divide both sides of -2 x = 8 by -2:
(-2 x)/(-2) = 8/(-2)
(-2)/(-2) = 1:
x = 8/(-2)
The gcd of 8 and -2 is 2, so 8/(-2) = (2×4)/(2 (-1)) = 2/2×4/(-1) = 4/(-1):
x = 4/(-1)
Multiply numerator and denominator of 4/(-1) by -1:
Answer: x = -4
We want to translate the given statement into an algebraic expression.
The expression is:
d = 0.45*L
---------------------------------
When we have a discount of an X% on a given value V, that discount will be:
D = (X%/100%)*V.
Here we have:
<em>"A </em><em>discount</em><em> of a 45% on the list price L"</em>
The discount will be given by:
d = (45%/100%)*L = 0.45*L
d = 0.45*L
This is the expression we wanted to get.
