X= 65
Explanation:
Simplify both sides of equations
3(x)+7)(2)+8=440
6x+42+8=440 (Distribute)
(6x)+(42+8)=440
(Combine Like Terms)
Step 2: subtract 50 from each side
6x+50−50=440-50 6x=390
Step 3: Divide both sides by 6
6x/6 = 390/6
Problem 10
You are correct. You divide 360 over the exterior angle measure to get 360/72 = 5
=========================================================
Problem 11
x = 33 is correct as this angle is an alternate interior angle pair with the 33 degree angle up top
y = 38 is correct since y+33+109 = 180 solves to y = 38. In other words: 38+33+109 = 180
z = 109 is correct. The opposite angles of a parallelogram are congruent
Answer:
Option B. 373.80 square centimeters
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The surface area of the figure is equal to the area of its 5 faces (3 rectangular faces plus 2 triangular faces)
step 1
Find the area of its 3 rectangular faces



step 2
Find the area of its 2 triangular faces


step 3
Find out the surface area

substitute the values


Remove the radical by raising each side
6^2= square root 8x-4 ^2
36= 8x-4
40= 8x
