4(0.1)+4(0.01)+2(0.25)+0.05+3(2)+4(1)
=10.99
Expand (x+2)^2: x^2 + 4x + 4 : remember that (a+b)^2 = a^2 + 2ab + b^2
So: x^2 + 4x + 4 - x^2 = 60
Answer:
the rotation angle is double the angle between the lines
Step-by-step explanation:
The Reflections in Intersecting Lines Theorem will tell you that the effective angle of rotation is double the angle between the intersecting lines. Here, the figure is effectively rotated 144°, not 72°. If a 72° rotation is desired, the lines need to intersect at an angle of 36°.
Answer:
D: 14q + 21√qr
Step-by-step explanation:
We want to find the product of;
(2√q + 3√r) and 7√q.
Where p and q are integers.
Using distributive property, we have;
(2√q × 7√q) + (3√r × 7√q)
>> 14q + 21√qr
Correct option is D
