4a²=144
a²=144/4
a²=36
a=⁺₋√36
a=⁺₋6
Answer: we have two values for a; a=-6; and a=6
we check it out:
if a=-6
4(-6)²=4*36=144
if a=6
4(6)²=4*36=144
Answer:
19
Step-by-step explanation:
The vertical axis of a histogram indicates the total amount of people that meet the weights indicated in the x-axis in the analysed population. From data we can construct the following table:
x-axis y-axis
115 1
135 4
155 3
175 1
195 5
215 2
235 3
So there are: 1+4+3+1+5+2+3 = 19 team members included in the histogram.
The distance between (-11, -20) and (-11,5) is 25. Since both of the x values are the same, we know that they are both on the same x line. For the y values, -20 and 5, Their difference from each other is 25. Therefore, the distance between those coordinates are 25.

Here's the solution,
the volume of the given figure is :
=》
volume of pyramid :
=》
=》
=》
=》
volume of pyramid = 40 cm³
now, volume of rectangular prism :
=》
=》
=》
volume of rectangular prism = 40 cm³
volume of composite figure = 40 + 40
=》80 cm³
