Answer:
I think the answer is 664....but I'm nt sure. Plz don't blame me if I'm wrong lol
Step-by-step explanation:
12x8x7= 672
672- 8= 664
Answer:
x=9
Step-by-step explanation:
(x+3)/2=6
Multiply each side by 2
2*(x+3)/2=6*2
x+3 = 12
Subtract 3 from each side
x+3-3 = 12-3
x = 9
Answer: x = 1
3x + 4 = 7
subtract 4 from both sides
3x = 3
x = 3/3 = 1
Answer:
627square inches
Step-by-step explanation:
Area of the composite figure.. = area of triangle + area of parallelogram
Since the triangle is an equilateral triangle;
Area of the triangle = r²sintheta
Area of the triangle = 18²sin60
Area of the triangle = 324sin60
Area of the triangle = 324(0.8860)
Area of the triangle = 280.584 square in
Area of the triangle = 281 square inches
Area of parallelogram = absintheta
Area of parallelogram = 20(20)sin60
Area of parallelogram = 400(0.8660)
Area of parallelogram = 346.4square inches
Area of parallelogram = 346 square inches
Area of the figure = 346 + 281
Area of the figure = 627square inches
Answer: v=-81.92
Step-by-step explanation:
![\displaystyle\\7+\frac{v}{8} =-3.24\\\\7+\frac{v}{8}-7 =-3.24-7\\\\\frac{v}{8} =-10.24\\\\\frac{v}{8} =-10.24](https://tex.z-dn.net/?f=%5Cdisplaystyle%5C%5C7%2B%5Cfrac%7Bv%7D%7B8%7D%20%3D-3.24%5C%5C%5C%5C7%2B%5Cfrac%7Bv%7D%7B8%7D-7%20%3D-3.24-7%5C%5C%5C%5C%5Cfrac%7Bv%7D%7B8%7D%20%3D-10.24%5C%5C%5C%5C%5Cfrac%7Bv%7D%7B8%7D%20%3D-10.24)
Multiply both parts of the equation by 8:
![\displaystyle\\(\frac{v}{8})(8)=(-10.24)(8) \\\\v=-81.92](https://tex.z-dn.net/?f=%5Cdisplaystyle%5C%5C%28%5Cfrac%7Bv%7D%7B8%7D%29%288%29%3D%28-10.24%29%288%29%20%5C%5C%5C%5Cv%3D-81.92)
