Novay_Z [31]

Answer:

Volume = 150 m^2

Step-by-step explanation:

Using Volume formula of prism, we get L*W*H, but since we know the area of the base is L*W, which is 12.5, we multiply 12.5 by 12 to get 150 m^2.

Whats the answer for this??
aniked [119]

Step-by-step explanation:

what do you mean "what's the answer for this ?"

you only need to put 3 in place of x (that's what is meant by "x is 3" or x = 3) and then simply calculate.

you know what "squaring" ("something to the power of 2" or x²) means ? it means that you have to multiply that "something" by itself.

y = 3² + 11 = 3×3 + 11 = 9 + 11 = 20

that's all there is to this.

I need step by step explanation for this!! >33
Masteriza [31]

Answer:

458

Step-by-step explanation:

There are only 4 3-digit numbers that have a 5 in the ten’s place and the one’s place is twice of the hundreds place.  

152, 54, 356, and 458

If we reverse the order of the digits, we see that 458 becomes 854.

854-458=396

Nina knows that the average of the x-intercepts represents the line of symmetry for a quadratic function through the x-axis. Whi
Romashka [77]

Answer:

\bf \displaystyle\frac{5+1}{2}=\displaystyle\frac{6}{2}=3

Step-by-step explanation:

The x-intercepts are the values of x for which y=0, that is f(x)=0.

The x-intercepts of  

\bf f(x)=4x^2-24x+20

are the values of x such that

\bf 4x^2-24x+20=0

Divide both sides by 4 to simplify a little

\bf x^2-6x+5=0

Solve the quadratic equation

\bf x=\displaystyle\frac{-(-6)\pm\sqrt{(-6)^2-4*1*5}}{2*1}=\displaystyle\frac{6\pm\sqrt{36-20}}{2}=\\\\=\displaystyle\frac{6\pm\sqrt{16}}{2}=\displaystyle\frac{6\pm4}{2}

and you get the 2 x-intercepts

x =10/2  and x = 2/2  

or

x = 5 and x = 1

The average is the midpoint

\bf \displaystyle\frac{5+1}{2}=\displaystyle\frac{6}{2}=3
