Answer:
90 cubic inches
Step-by-step explanation:
V = 1/3 · area of base · height
V = 1/3 · 18 · 15
V = 6 · 15
V = 90
X-3=66
x=69
69+41+(y-9)=180
110+y-9=180
101+y=180
y=79
Answer:
<h2>A) 67</h2>
Step-by-step explanation:
The sum of the angles measures at one side of the parallelogram is 180°.
Therefore we have the equation:
x + 113 = 180 <em>subtract 113 from both sides</em>
x + 113 - 113 = 180 - 113
x = 67
You have 9n and -7 in total so the answer is 9n-7. You add up all the numbers and then add up the numbers with n attached to them
