Answer:

126.5

Step-by-step explanation:

first, break the figure into a triangle and a square (do I have to tell u where)

the square: 11*8=88

the triangle: 11*7=77          77/2= 38.5

88+38.5= 126.5

The solution is, the area of the given figure is : 126.5cm^2.

What is area ?

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

given that,

we need to find  the area of the given figure.

so, we have ,

first, break the figure into a triangle and a square

now, we get,

the square:

area= 11*8

       =88

and, we have,

the triangle:

area =1/2* 11*7

       =1/2*77          

       = 77/2

       = 38.5

so, we get,

the area of the given figure is:

88+38.5= 126.5

Hence, The solution is, the area of the given figure is : 126.5cm^2.

The value of the x is -2 after solving the linear equation by using the elimination method.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The linear equations are:

2x+3y=8

6x−5y=−32

3X(2x+3y=8)

6x + 9y = 24

6x−5y=−32

14y =  56

y = 4

x = -2

Thus, the value of the x is -2 after solving the linear equation by using the elimination method.

Chicago, Illinois, has an elevation of 600 feet above sea level (zero feet). The elevation of Desert Shores, California, is 800 feet less than the elevation of Chicago.

Which statement is true about Desert Shores?

the elevation is -200 feet

the elevation is 200 feet

the elevation is at 1400 feet

the elevation is at -1400 feet

Answers

Answer:

The elevation is -200 feet.

Step-by-step explanation:

600 - 800 = -200

-200, since you start off with 600 ft and your taking away 800 it would become negative so, 600-800= -200
