Answer:
372 in ^2
Step-by-step explanation:
Wrapping a present is surface area
SA = 2( lw+wh+hl)
= 2 ( 12*3 + 12*10 + 3*10)
= 2 ( 36+120+30)
= 2 (186)
= 372 in ^2
Answer:
w = -1/5
OR
w = -3
Step-by-step explanation:
Given equation:
−16w-3 = 5w²
Solution:
Subtracting 5w^2 from both sides,we get
- -16w-3-5w² = 5w² - 5w²
- -5w²-16w-3=0
Factor the LHS of this equation using middle term factor:
Now,
Solving for equation 1:
Solving for equation 2:
<h3>The value of y is equal to 1.</h3><h3>The value of x is equal to 4.</h3>
Because both equations have a term that will cancel out if they're added together, we're going to add both equations together.
-5x + 5x = 0
13y + 4y = 17y
-7 + 24 = 17
17y = 17
Divide both sides by 17.
y = 1
Now that we have a constant value of y, we can solve for x.
-5x + 13(1) = -7
-5x + 13 = -7
Subtract 13 from both sides.
-5x = -20
Divide both sides by -5.
x = 4
