B is the answer, 1 4/5 is equal to 1.8 so you are looking for something between 1.4-1.8 and 1.34 is not in that range
For this case we have the following expression:
S.A = 2x ^ 2 + 2x *y + 2x * y
Rewriting we have:
S.A = 2x ^ 2 + 4x *y
S.A = 2 (x ^ 2 + 2x * y)
Where,
x: side length of a square base
y: height of the prism
Answer:
an expression for the total Surface Area (SA) of a rectangular prism is:
S.A = 2 (x ^ 2 + 2x * y)
Answer:
Step-by-step explanation:
m∠2 = 
(55+41)
m∠2 = (96)
m∠2 =48°
m∠1 = 180-48 = 132°
Answer:
19) x = 15
20) x = 16
21) Never, because supplementary means 2 angles that add up to 180 degrees, and obtuse angles are angles that are more than 90 degrees.
22) Never, because complementary means 2 angles that form a 90 degree angle, but vertical angles are across from each other and will never meet, otherwise it's not called vertical angles.
Step-by-step explanation:
19) Supplementary angle = 2 angles that add up to 180 degrees. Therefore, the equation is <em>45+9x = 180. </em>To solve for x, subtract 45 from 180, which equal to 135. Then, divide 135 by 9, which equal to 15.
20)Complementary angle = 2 angles that add up to 90 degrees. Therefore, the equation is <em>4x+26 = 90. </em>To solve for x, subtract 26 from 90, which equal to 64. Then, devide 64 by 4, which equal to 16.
I can't really do #23, but I hope those above helps^
To find the solution to a set of linear equations, set them both to y=kx form
In this case,
1) 3x+y=15 would be y= -3x+15
2) 2x+2y=6 would be y= -x+3
3) Set them equal to each other
4) -3x+15= -x+3
5) x=6
So now we know the x coordinate as 6
Plug in this x value in one of the y= equations
6) (-3×6)+y=15
(solve for y)
y= 33
Therefore, the solution is (6,33)
