Answer:

The missing length is 2x+5

Step-by-step explanation:

Given equation of volume of cuboid is V= 2x^{3} +17x^{2} +46x+40

Figure show that

Length of cuboid is ?

Width of cuboid is (x+4)

Height of cuboid is (x+2)

The volume of cuboid is given by

V=Length x Width x Height

Let Length be (bx+a)

The volume of cuboid will be

V=(bx+a)(x+4)(x+2)

V=(bx+a)[x^{2}+4x+2x+8 ]

V=bx[x^{2}+6x+8]+a[x^{2}+6x+8]

V=[bx^{3}+6bx^{2}+8bx]+[ax^{2}+6ax+8a]

V=[bx^{3}+(6b+a)x^{2}+(8b+6a)x+8a]

On comparing coefficient with given equation of volume

We get,

b=2 and 8a=40

Therefore, the value of a is 5 and b is 2

Thus, The missing length is bx+a=2x+5

Jerry had 1 gallon of ice cream. He used 4/10 gallon to make chocolate milkshake and 0.30 gallon to make vanilla milkshake. How
stiv31 [10]
0.30 is the same as 3/10 so then you would add 3/10 and 4/10 which equals 7/10 which then gives you with 3/10 ice cream left

Find the value of c that makes each trinomial a perfect square<br> x^2-19x+c<br> Please Help! :)
tensa zangetsu [6.8K]

The value of c is \frac{361}{4}

Explanation:

Given that the trinomial is x^2-19x+c

We need to determine the value of c such that the trinomial is a perfect square.

The value of c can be determined using the formula,

c=(\frac{b}{2})^2

From the trinomial, the value of b is given by

b=-19

Substituting the value of b in the above formula, we have,

c=(\frac{-19}{2} )^2

Squaring both the numerator and denominator, we have,

c=\frac{361}{4}

Thus, the value of c is \frac{361}{4} which makes the trinomial a perfect square.

After 24 pencil had sharpened, the pencil sharpener receptacle is full. If receptacle is emptied in average of twice a day, how
stiks02 [169]

Answer:

12 Pencils Sharpened

Step-by-step explanation:

Since the sharpener receptacle is emptied out 2 times every day.

Do 24*2 to get 48 pencils sharpened each day.

Now do 48/20 to get how many pencils a single person sharpens each day. Resulting in 2.4 pencils each day for 1 person.

Multiple 2.4 by 5 (Amount of days) to get 12 pencils in 5 days.

How to find slope when giving two equations that equal each other?
9966 [12]

slope formula.:

m = (y_2 - y_1) / (x_2 - x_1)

so you just need two points from whatever function you have

Or if you already have the function formula, then just the number of the first term (if your function is this: y=ax^2 + bx + c then the a is the slope)

Hope this helps!
