Answer:
m2 = 145
m3 = 145
m4 = 35
Step-by-step explanation:
m<1 = m<4 because of vertical angles
m<2 + m<1 = 180
m<2 + 35 = 180
m<2 = 145
m<2 = m<3 because of vertical angles
I would say the answer is either c or a, can’t see the video so i can’t really determine
V = s^3= 343 = 7×7×7
S = 7 cm
Answer:
see explanation
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (3, 6)
m = 
= 
Since division by zero is undefined then the slope of the vertical line is undefined.
The best way to multiply complicated problems mentally* is to break them into chunks.
Start with 20 times 8 to get 160, and then 8 times 5 to get 40. Add these together to get 200. 200 times 3 is 600, and 20 times 200 is 4000. Add these together to get your final answer, 4600.
In other words 8 x 20 + 8 x 5 = 200 200 x 3 + 200 x 20 = 4600
*I assumed you meant mentally, because otherwise you'd just multiply longhand, multiplying two of the three numbers and then multiplying their product with the third.
