Answer: There are 3 strips that can be cut from the roll of ribbon.
Step-by-step explanation:
since we have given that
Length of a ribbon is given by
Length of pieces of ribbon cut into strips is given by
So, we need to find the number of strips that can be cut is given by
Hence, there are 3 strips that can be cut from the roll of ribbon.
Answer: THIRD OPTION.
Step-by-step explanation:
The missing figure is attached.
You can observe in the figure two equal right triangles: RST and RSV.
Notice that:
Knowing that:
You can substitute values into the equation and solve for "x":
Now, you can identify in the figure that:
Having the value of "x" calculated above, you can subsitute into the equation and evaluate, in order to find the length of segment RV:
Since:
You get that:
Finally, you must add RT and RV in order to find the length of the segment TV. This is:
Answer:
<h2>b = 2</h2>
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
To add the polynomials you can only add like terms. Like terms are terms that have the same variables and exponents. Only -5 and 4 are like terms. So leave the other terms alone.
The sum is 11x^2 + x - 1.
