Answer:

2x(x + 2)(x + 3)

Step-by-step explanation:

2x³ + 10x² + 12x ← factor out 2x from each term

= 2x(x² + 5x + 6) ← factor the quadratic

Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)

The factors are + 2 and + 3 , since

2 × 3 = 6 and 2 + 3 = 5

x² + 5x + 6 = (x + 2)(x + 3)

Then

2x³ + 10x² + 12x = 2x(x + 2)(x + 3)

Answer:

41/45

Step by Step Explanation:

Add: 8/

10

+ 1/

9

= 8 · 9/

10 · 9

+ 1 · 10/

9 · 10

= 72/

90

+ 10/

90

= 72 + 10/

90

= 82/

90

= 2 · 41/

2 · 45

= 41/

45

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 9) = 90. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 9 = 90. In the following intermediate step, cancel by a common factor of 2 gives 41/

45

In other words - eight tenths plus one ninth = forty-one forty-fifths.

Answer: 500

Step-by-step explanation:

Answer:

155°

Step-by-step explanation:

The total of the angles in a triangle is 180° and also any pair or trio of angles that maje a straight angle also add up to 180°. So look for those set ups.

The left most triangle has an angle marked 35° and also a right angle is labelled. The right angle is 90° So the third angle must be 180° - (35°+90°)

180° - 125°

55°

The 55° angle(we just found) and the 60° angle (labelled) and a third unmarked angle all together maje a straight angle, 180°.

So we can calculate the third angle, which is an angle in the other shown triangle.

180° - (55° + 60°)

180° - 115°

65°

This triangle also has a right angle in it. And the third angle can be calculated in the same way.

180° - (65° + 90°)

180° - 155°

25°

Last time, the 25° angle and the angle marked x make a straight angle.

180° - 25°

155°

Answer:

gradient = -3

Step-by-step explanation:

Find the gradient using the formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where [tex]m[/tex] is the slope and [tex](x_1, y_1)[/tex] is one point and [tex](x_2, y_2)[/tex] is the other point.

Let [tex](x_1, y_1)[/tex] = (-4, 4)  and  [tex](x_2, y_2)[/tex] = (-3, 1)

Therefore, [tex]m=\frac{1-4}{-3--4}=\frac{-3}{1} =-3[/tex]

Now use the equation of line formula:  [tex]y-y_1=m(x-x_1)[/tex]

[tex]y-4=-3(x--4)[/tex]

[tex]y-4=-3x-12[/tex]

[tex]y=-3x-8[/tex]

Answer:

R125 profit was made

Step-by-step explanation:

R375-250=R125

R125+R250=R375

Triangles are shapes with three sides and angles

The value of B is 16.3 degrees

The given parameters are:

a = 64

b = 18

c = 63

Next, we apply the following cosine formula

[tex]b^2 = a^2 + c^2 - 2ac\ cos(B)[/tex]

So, we have:

[tex]18^2 = 64^2 + 63^2 - 2 * 64 * 63 \ cos(B)[/tex]

Evaluate the exponents

[tex]324 = 8065 - 8064\ cos(B)[/tex]

Collect like terms

[tex]324 - 8065 = - 8064\ cos(B)[/tex]

[tex]-7741 = - 8064\ cos(B)[/tex]

Solve for cos (B)

[tex]\cos(B) =0.9599[/tex]

Take the arccos of both sides

[tex]B =cos^{-1}(0.9599)[/tex][tex]B = 16.3[/tex]

Hence, the value of B is 16.3 degrees
