Answer:
I'm pretty sure it's the last one.
Step-by-step explanation:
The expression that represents the volume of the composite figure is (8*6*4)+ 1/3 * (8*6*6).
<h3>What will be the volume of the composite figure?</h3>
The volume of the composite figure will be the sum of the volume of the cube and the volume of the pyramid.
Volume of the cube = length*breadth*height
So, the volume of the cube = 8*6*4
The volume of the pyramid = 1/3 *(area of the base) * (height of the pyramid)
Area of the base of the pyramid = 8*6
Height of the pyramid = total height - height of the cube
Height of the pyramid = 10-4 =6
So, the volume of the pyramid = 1/3 * 8*6*6
So, total volume = (8*6*4)+ 1/3 * (8*6*6)
Hence, the expression that represents the volume of the composite figure is (8*6*4)+ 1/3 * (8*6*6).

Answer:
-14
Step-by-step explanation:
First of all, we know that 5x^2+ ax+7x +5=0 only has one root. That means that b^2 - 4ac=0, and we can use this to find the discriminant, ax + 7x.
Now, if we simplified 5x^2+ ax+7x +5=0, by dividing it all by 5, it would be x^2+(a+7)/5x + 1 = 0.
After, we can plug what we know into the formula, b^2 - 4ac=0. It would be:
(a+7)^2 / 25 - 4 = 0
(a+7)^2 / 25 = 4
(a+7)^2 = 100
Since this is a square root, a+7 can be both negative or positive.
a+7= 10, or a+7 = -10
a=3, or a=-17
The question asks for the sum of a, which is 3 + (-17) = -14
Therefore, the answer is -14.

m=-(5/4)
From left to right, (1,3) is first and then comes (5,-2). Always remember when finding slopes without equations, the rule is RISE over RUN, to the numerator and denominator, respectively.
The y value of the second coordinates becomes negative which is unlike the y value in the first coordinates, which means our slope is downward, meaning it has a negative sign in front.
In every slope, there’s a numerator, being the rise, and a denominator, being the run.
To find the rise, we must look at the y values. Starting at 3 going to -2 has a space of 5 units, making that our numerator.
To find the run, the first x value is 1 and the second is 5, making a space of 4, which is out denominator.
With these two numbers and the negative sign, we get -(5/4) as our slope.
