Answer:
Add 
Step-by-step explanation:
The polynomial
can be added to eliminate the x terms by adding the additive inverse. We add
which has the inverse sign value of the polynomial terms.


When we simplify, this leaves
without an x term.
Answer:
Step-by-step explanation:
x=100 (vertically opposite angle)
Answer:
- resistance: (2r +5)
- current: (3i +4)
Step-by-step explanation:
The factors of the given expression are ...
6ir +15i +8r +20 = (3i +4)(2r +5)
Which factor is current and which is resistance is not clear. Usually, resistance is referred to using the variable r, so we suppose the expressions are supposed to be ...
resistance: (2r +5)
current: (3i +4)
15% of 26.51 is 3.9765. Kevin left a tip of $4
The height of the ramp of Raúl is calculated as; 8ft
<h3>How to use the principle of similar triangles?</h3>
Both big and small triangles are similar triangles because all three of their corresponding angles are congruent.
Now, to get the height we will use the concept of similar triangles to get;
h/2 = 12/3
Cross multiply to get;
h = 24/3
h = 8 ft
Thus, the height of the ramp of Raúl is 8ft.
