Answer:

3.6 \:  \: cm

Step-by-step explanation:

area \\ 4.5 =  \frac{1}{2}(a + b ) \times h \\ 4.5 =  \frac{1}{2} (1 + 1.5) \times h \\ 4.5 =  \frac{1}{2}  \times 2.5 \times h \\ 4.5 =  \frac{2.5h}{2}  \\ 4.5 = 1.25h \\  \frac{4.5}{1.25}  =  \frac{1.25h}{1.25}  \\ h = 3.6 \: cm

hope this helps

brainliest appreciated

good luck! have a nice day!

Answer:

3.6 cm

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2)*h

We know the area of 4.5  and the top is 1 and the bottom is 1.5

4.5 = 1/2 (1+1.5) h

4.5 = 1/2 (2.5) h

4.5 =1.25h

Divide each side by 1.25

4.5/1.25 = 1.25h/1.25

3.6 =h

Determine whether the algebraic expression is a linear expression.<br> Explain.
eimsori [14]

An equation that forms a straight line on a graph.


More precisely, a linear equation is one that is dependent only on constants and a variable raised to the first power. For example, y=6x+2 is linear because it has no squares, cubes, square roots, sines, etc. Linear equations can always be manipulated to take this form:


ax+b=0

You won't always see linear equations written exactly like that, but keep in mind that we can manipulate equations to put them in a particular form if necessary.


Linear equations are often written with more than one variable, typically x and y. Such equations will have many possible combinations of x and y that work. When those points (known as coordinate pairs) are plotted on an x-y axis, they will form a straight line. Let's take a look at this graphically below. The two equations drawn are linear. Note that one is in the form y=3 (it is dependent on just a constant, 3), and the other equation is y=0.75x−0.5 (a linear term and a constant).

Olin [163]
I think its 206 because you'll have to change  5% into a decimal and you'll
get 0.05 because you move the decimal place to the left 2 times. Then multiply
2,600 to 0.05 to get what the population decreasing for a year, (130) then multiply is by 2 (for 2 years) and you'll get
260 students.
