Answer:
x = 7
Step-by-step explanation:
x+16 = 4x-5
7+16=23
4x7=28-5=23
Vertical angle theorem states that angles vertically opposite to one another are equal
<u>Answer:</u>
Distance = 3r
<u>Step-by-step explanation:</u>
We are to write an algebraic expression and then simplify it for the given situation:
<em>The distance traveled by a train in three hours with a constant speed of r miles per hour.</em>
We know the formula of distance linking the speed and the time.
Distance = speed × time
Substituting the given values to get:
Distance = r × 3
Distance = 3r
Method for SA of cylinder=
2 x pi x r x h + 2 x pi x r^2
SA = 2 x pi x 4 x 10 + 2 x pi x 4^2
= 351.9 cm^2
Hope this helps!!
Answer:
1. 3x + 2 - First degree
2. 4x3 + 17x - 5 - Third degree
3. 13x" + 5xn-2 - Second degree
4. 0.55x2 + 0.7x - Second degree
5. 7x3 + 10x + 15 - Third degree
Step-by-step explanation:
The degree of a polynomial is given by the highest power of the given variable (x in this case) in the polynomial. All the elements are considered in selecting the highest power of x in the polynomials.
Considering all; the highest degree of x in the polynomials given is 3 while the lowest is 1 hence we have polynomials ranging from the first to third degrees.
