Find the sum: 2 + 9 + 16 + ... + 37

iris [78.8K]

Step-by-step explanation:

Sum of arithmetic terms = n/2 × [2a + (n - 1)×d], where 'a' is the first term, 'd' is the common difference between two numbers, and 'n' is the number of terms.

this is the same as n/2 × (a1 + an), because

an = a1 + (n-1)×d

so, for the series above :

a or a1 = 2

d = 7, as every new term is the previous term plus 7.

for n

37 = a1 + (n-1)×d = 2 + (n-1)×7

and now solve for n

35 = 7n - 7

42 = 7n

n = 6

so, the sum of all terms is

6/2 × (2+37) = 3×39 = 117

What is the equation of the line that is

Lena [83]

Answer:

y = 1x - 3

Step-by-step explanation:

Note that the given line has slope +1.

Any line parallel to this line must also have slope +1.

Apply the slope-intercept form y = mx + b:

Inserting -3 for y, 0 for x and 1 for m, we get the y-intercept

-3 = 1(0) + b, which tells us that b = -3 and that the desired equation is

y = 1x - 3

Find the area of a triangle who's side lengths are 13, 14, and 15. (The questions doesn't tell the type of triangle.)

Y_Kistochka [10]

Answer:

84 square units.

Step-by-step explanation:

<h2>Area of scalene triangle:</h2>

$\sf \boxed{\bf Area = \sqrt{s*(s-a)(s-b)*(s-c)}}$

Here, a, b and c are the sides of the triangle. s is the semi perimeter.

a = 13

b = 14

c = 15

$\sf s= \dfrac{a+b+c}{2}\\\\ =\dfrac{13+14+15}{2}\\\\=\dfrac{42}{2}\\\\s = 21$

s -a = 21 - 13 = 8

s -b = 21 - 14 = 7

s - c = 21 - 15 = 6

$\sf Area = \sqrt{21*8*7*6}$

$= \sqrt{ 7* 3 * 2 * 2 * 2 * 7 * 2 * 3}\\\\=7 * 3 *2*2\\\\= 84 \ square \ units$
