Perimeter of a rectangle:
P=2I+2W=2(I+w)
But if the length and width of a rectangle are both double, then we would have:
Length=2I
width=2w
Therefore, its perimeter would be:
P=2(2I+2w)=4(I+w)
the old perimeter was P=2(I+w) and the new perimeter is P=4(I+w)=2[2(l+w)]
There the perimeter is twice as great.
Answer: C) the perimeter is twice as great.
Answer:
x=2
Step-by-step explanation:
The angle formed by two tangents intersecting outside of a circle is half the difference of the intercepted arcs.
This implies that:
We need to simplify this ad solve for x to get:
Group the similar terms to get:
232=116x
Divide by 116 to get:
x=2
Answer:
-2744/405
Step-by-step explanation:
Answer:
-3x + 6
Step-by-step explanation:
-3(x - 2) to find the equivalent of this expression, we need to multiply inside the parenthesis with -3 (with both x and -2)
-3(x - 2 = -3x + 6 (two negative expressions multiplied results in positive)
A complement is angle that can be added to another to equal 90 degrees.
So two times the same number would equal 90.
90 / 2 = 45
The angle that is its own complement is 45 degrees.
