Answer:

\Huge{\bf  \boxed{\bf 3 \times (z - 6)}}

Step-by-step explanation:

Topic- Algebra

<u>Subtract 6 from z will be rewritten as,</u>

\sf \longmapsto \: z - 6

On this algebraic expression, There is one term and a number.We can't simplify it.<em>(If we could Simplify the given expression then also we can't as there is a condition)</em>

<u>Then , We have asked to multiply the result (z-6) by 3.</u>

That is,

\sf \longmapsto3(z - 6)

But,the condition is that we should not simplify any part of the given expression.So we can't simplify this expression.

\sf \longmapsto3 \times (z - 6)

I hope this helps!

Please let me know if you have any questions.I am joyous to help!

You are planning to make an open rectangular box from a 25​-in.-by-49​-in. piece of cardboard by cutting congruent squares from
Darya [45]

Answer:

The dimensions of the box are 38.48 x 14.48 x 5.26 in.

Step-by-step explanation:

We will have a piece of cardboard with squares of side x cut from the corners to make a open box.

The volume of the box can be written as:

V=A\cdot B\cdot x\\\\V=(49-2x)\cdot (25-2x)\cdot x\\\\V=x\cdot (4x^2-2x*(49+25)+49*25)\\\\V=4x^3-148x^2+1225x

To calculate the maximum volume, we derive and equal to zero

dV/dx=12x^2-296x+1225=0

We apply the quadratic equation to know the roots of the equation

x=\frac{-b\pm\sqrt{b^24ac}}{2a}\\\\x=\frac{296\pm\sqrt{296^2-4*12*1225}}{2*12}  =\frac{296\pm\sqrt{87616-58800}}{24}= \frac{296\pm\sqrt{28816}}{24}\\\\x=\frac{296\pm169.75}{24}= 12.333\pm7.073\\\\\\x_1=12.333+7.073=19.406\\\\x_2=12.333-7.073=5.26

The first solution is physically impossible, as the side that is cut would be bigger than 25.

So the real solution is for x=5.26 in.

Then, the dimensions of the box are:

A=49-2x=49-2*5.26=49-10.52=38.48\\\\B=25-2x=25-10.52=14.48

H(a) = 2a+ 5g(a) = 3a−5Find h(a)+ g(a)
Alexandra [31]

Answer:

5a

Step-by-step explanation:

h(a) = 2a+ 5

g(a) = 3a−5

h(a)+g(a)

(2a+5)+(3a-5) (substitution)

2a+5+3a-5 (open parentheses)

5a+0 (solve)

5a
