It’s negative by the looks of it.
If you solve it you get -2.5
I hope it’s correct!
Move all terms not containing U to the right side of the equation.
Exact Form:
U = 1/2
Decimal Form:
U = 0.5
Answer: 6x^2
Step-by-step explanation:
Answer:
Shape 1: 25.915
Shape 2: 102.85
Shape 3: 142
Step-by-step explanation:
For shape 1, you have to divide 7.1 to get half the width of the triangle. You get 3.55 from that, and then finding the triangle itself you have to do 7.3*3.55 to get 25.915. For shape 2, you first do the harder parts (the triangles) and since there is two of them we don't need to half the width of each triangle. But first to get the width, we need to do 20-17.4=2.6. But since there are 2 triangles we need to divide that by 2 to get 1.3. Then you multiply that by 5.5 to get the final area of both triangles which is 7.15. Next you simply find the rectangle which is 17.4*5.5=95.7. You add the triangles area to get 102.85. Finally for shape 3 you simply do 7.1*20=142.
Answer:
1/4
Step-by-step explanation:
Find common denominators. Note that what you multiply (or divide) from the denominator, you must also do the same to the numerator.
In this case, the common denominator would be 4. Multiply 2 to both the numerator & denominator of (-1/2):
(-1/2) * (2/2) = (-1 * 2)/(2 * 2) = -2/4
Subtract across:
3/4 - 2/4 = (3 - 2)/4 = 1/4
1/4 is your answer.
