A cuboid with a volume of 924cm^3 has dimensions 4cm, (x+1)cm and (x+11). Show clearly that x^2+12x-220=0 solve the equation by factorisation, making sure you show the factorisation. Finally, find the dimensions of the cuboid,

Answers

Answer:

[tex]x^2+12x-220=0[/tex] -- Proved

[tex]x = 10\ \ \ x = -22[/tex]

Step-by-step explanation:

Given

[tex]Volume = 924cm^3[/tex]

[tex]Dimension: 4cm; (x+1)cm; (x+11)cm[/tex]

Required

Show that [tex]x^2+12x-220=0[/tex]

The volume is calculated as:

[tex]4 * (x + 1) * (x + 11) = 924[/tex]

Open the brackets

[tex](4x + 4) * (x + 11) = 924[/tex]

[tex]4x^2 + 44x + 4x + 44 = 924[/tex]

[tex]4x^2 + 48x+ 44 = 924[/tex]

Collect Like Terms

[tex]4x^2 + 48x+ 44 - 924=0[/tex]

[tex]4x^2 + 48x -880=0[/tex]

Divide through by 4

[tex]\frac{4x^2}{4} + \frac{48x}{4} -\frac{880}{4}=0[/tex]

[tex]x^2+12x-220=0[/tex]

Solving further:

Expand the expression

[tex]x^2 + 22x - 10x - 220 = 0[/tex]

Factorize:

[tex]x(x + 22) - 10(x + 22) = 0[/tex]

[tex](x - 10)(x + 22) = 0[/tex]

Split:

[tex]x - 10 = 0;\ \ \ x + 22 = 0[/tex]

[tex]x = 10\ \ \ x = -22[/tex]

Answer:

Step-by-step explanation:

...................

The measure of angle U is 74 degrees.

What is an angle?

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

to determine the measure of angle U:

From the question, we have the following parameters that can be used in our computation:

△PQR ≅ △STU

If m ∠P = 62 degrees and m ∠Q = 45 degrees

The above parameters mean that

P = S Q = T and R = U

So, we have

U = R = 180 - P - Q -- by the angles in a triangle theorem

So, we have

U = 180 - 61 - 45

= 74

Evaluate

U = 74

Hence, the value of m ∠U is 74 degrees

Step-by-step explanation:

Column Vector

Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.

It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).

The vector directed from A to B is found by subtracting its corresponding coordinates:

[tex]\overrightarrow{AB }=<2-6,7-4>[/tex]

[tex]\overrightarrow{AB }=<-4,3>[/tex]

Now we express the vector as a one-column matrix as follows:

[tex]\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}[/tex]

Try finding how many meters they travel in ONE second) Mai and Priya were on scooters. Mai traveled 15 meters in 6 seconds. Priya travels 22 meters in 10 seconds.

Answers

Answer:

Mai travels 2.5 meters in 1 second

Priya travels 2.2 meters in 1 second

Step-by-step explanation:

Try finding how many meters they travel in ONE second) Mai and Priya were on scooters.

For Mai

Mai traveled 15 meters in 6 seconds.

Hence,

6 seconds = 15 meters

1 second = x meters

Cross Multiply

6x = 15 meters

x = 15/6

x = 2.5 meters

Hence, Mai travels 2.5 meters in 1 second

For Priya

Priya travels 22 meters in 10 seconds.

Hence,

10 seconds = 22 meters

1 second = x meters

Cross Multiply

10x = 22 meters

x = 22/10

x = 2.2 meters

Hence, Priya travels 2.2 meters in 1 second

What are the roots of the polynomial equation: 4k - 144 = 0 Show all of your work!

Answers

Answer:

k = ±6

Step-by-step explanation:

guess your question is 4k²–144 = 0??

4k² = 144

k² = 36

k²–36 = 0

(k+6)(k–6) = 0

k+6 = 0 | k–6 = 0

k = –6, k = 6.

Alternatively; k = ±6.
