Davis's claim was incorrect because a rectangle sometimes only have 2 congruent sides. Drawing a rectangle, the length/width would be longer than their length/width. Unless it is a square, it counts as correct as a square can be counted as a rectangle and a rectangle can not be counted as a square but anyways, congruent means equal sides. The rectangle, mostly drawn, only has two long sizes and two short sides, both opposides are equal. Hence, the claim Davis said is incorrect.

S = 2lw + 2wh + 2lh; solve for l
Pavel [41]

Answer:

l = (S - 2wh)/(2w + 2h)

Step-by-step explanation:

S = 2lw + 2wh + 2hl

S - 2wh = 2lw + 2hl

S - 2wh = l (2w + 2h)

(S - 2wh)/(2w + 2h) = l

⦁ Find the sum of the series . 15 sigma n=1, (2n-1) Show your work
sergejj [24]

Answer:

225

Step-by-step explanation:

The sum of this series is given by the formula:

S_n=\frac{n}{2}[2a+(n-1)d]

Where

S_n is the sum

a is the first term (we get this by plugging in n = 1 into "2n-1", we have 2(1) - 1 = 1)

n is the number of terms (the sum is defined for n = 1 to n = 15, so 15 terms)

d is the common different (the difference is successive terms. Here, 2nd term would be 2(2) - 1 = 3, and first term was 1, so d = 3 -1 = 2)

<em>plugging in the info, we will get the sum:</em>

<em>S_n=\frac{n}{2}[2a+(n-1)d]\\S_{15}=\frac{15}{2}[2(1)+(15-1)(2)]\\=225</em>

<em>The sum is 225</em>

You would use the sine rule. This is because the sine rule is when you know two of the angles on any triangle.
