Find the sum of the sequence. 42+43+44+45+...+107

8090 [49]

Answer:

4917

Step-by-step explanation:

Given sequence:

42, 43, 44, 45, ..., 107

This is AP with common difference of 1, the first term of 42 and the last term of 107

Number of terms:

107 - 42 + 1 = 66

Sum of the terms:

Sₙ= 1/2*n*(a₁+aₙ)

Sₙ= 1/2*66*(42+107) = 4917

Answer is: 4917

Answer:Hopes this helps!

6x²+2x-20=0

==>6x²+12x-10x-20=0

==>6x(x+2)-10(x+2)=0

==>(x+2)(6x-10)=0

==>x=-2 or x=5/3

draw a rectangle give the length and the width to show that it has an area of 12cm make sure one side is longer than the other t

Elden [556K]

To find area, you multiply length * width. There are 4 sides on a number, so we need to have a equation like this. x * x * y * y = 12cm. If we do 4 * 4, we get 8. We could also use 2 * 2 = 4. 8 + 4 = 12. So, width = 8, and length = 4.

Hope this helps! ☺♥

Answer:

The correct option is 3.

Step-by-step explanation:

From the given graph it is noticed that the related line passing through the point (-3,1) and (0,3).

If a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$
