Answer:
56
Step-by-step explanation:
Think of it this way, 7 times 10 is 70.
7*8 is 2 less 7s, or 14 less.
70-14=56
Or, a simpler way:
7*7 is 49(perfect square)
One more seven than that is 56.
These are just two ways I quikcly remember, because for some reason I struggle with 7 and 8 mulitplication.
Hope this helps!
Answer:
v= 17
Step-by-step explanation:
Start with the given equation.
19v – 18 = 16 + 17v
Move -18 to the other side, and swap it's sign.
19v = 16 + 18 + 17v
Move 17v to the other side and swap it's sign.
19v - 17v = 16 + 18
Combine like terms.
2v = 34
Divide by 2v.
v = 17
Answer:you just multiple use a calcultor
Step-by-step explanation:

<h3>STEP-BY-STEP EXPLANATION :- </h3>
We have been asked to find .
• In which quadrant does the terminal side of the angle 257° lie ?
- As we know that in the first quadrant angle is from 0 to 90 ° .
In the second quadrant angle is from 90 to 180°.
In the third quadrant angle is from 180 to 270° .
In the fourth quadrant angle is from 270 to 360° .
<h3>Hence,The Angle 257 will lie in the third Quadrant .....</h3>
