Easy geometry just find area shade boxes thank you plz help

45 square units

Step-by-step explanation:

To figure out the area of a trapezoid, the formula is. A= (b1 + b2)h ÷2 . b1 is the top side which is 7 units and b2 is the bottom side which is 11 units. The height (h) is a vertical line going from the top to the bottom which is 5 units. All you need to do now is plug in those numbers and solve the equation.

45 square units

Step-by-step explanation:

This shape can be broken down into two diffrent peices

The first peice is the rectangle

The second peice is the triangle

And both of these peices area's added together will yeild the total area

The rectangle is 7 units long and 5 units high, so it has an area of (7X5) = 35

The triangle is a little bit more complicated, it's formula is (BaseXHeight)/4

So all we need to do is plug in The base of the triangle = 4

And the Height of the trianlge = 5

So the triangles area is... (4X5)/2= 10

35+10=45 square units

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
