i don't know people are rude lol I tried at least
3x + 15 because u add all the x and then all real numbers
Both triangles area:
4.2 x 8.2 = 34.44
you don’t need to divide by two cause there’s two triangles anyways.
also, you get 8.2 by subtracting the total length by the top length. (13.5-5.3)
rectangle:
4.2 x 5.3 = 22.26
the total area is 56.7cm squared
Answer:
45°
Step-by-step explanation:
The hour hand makes a trip of 360° around the face of the clock in 12 hours, so in 4.5 hours will make an angle of ...
... (4.5/12)·360° = 135°
clockwise from straight up.
The minute hand makes that 360° turn in 1 hour, so in 30 minutes, it will be 180° clockwise from straight up.
The difference between the angles of the hands is ...
... 180° -135° = 45°
Answer:
Option B.
Step-by-step explanation:
If a quadratic equation is defined as
.... (1)
then the quadratic formula is
The given equation is
It can rewritten as
.... (2)
On comparing (1) and (2) we get
Using quadratic formula we get
Therefore, the correct option is B.
