Answer:
(4p^2-28pq)
Step-by-step explanation:
You have to times 4p by p meaning you get 4p squared as p multiplied by p gets you a squared. for the second half, 4x7= 28, and p multiplied by q is pq so it would be 28pq
You are looking for the circumference. which is C(circumference)=
x r (radius)
the radius is =to half of the diameter.
c=56.55
Answer:
x = 85
y = 65
Step-by-step explanation:
By interior angle sum property of a triangle.
y° + 25° + 90° = 180°
y° + 115° = 180°
y° = 180° - 115°
y° = 65°
y = 65
By remote interior angle theorem of a triangle:
x° = y° + 20°
x° = 65° + 20° (since y = 65)
x° = 85°
x = 85
Answer:
Step-by-step explanation:
40n + 30 = -170
40n + 30 = -170
40n = -200
n = -5
