(x + 2)(x + 3)(x + 4) can be written in the form x + ax² + bx + c
where a, b and care positive integers.
Work out the values of a, b and c.
Answer:
[tex]a=9, b=26, c=24[/tex]
Step-by-step explanation:
Let's expand the expression bit by bit.
[tex](x+2)(x+3)=(x)(x)+(x)(3)+(2)(x)+(2)(3)=x^2+5x+6[/tex] by FOIL.
We have that [tex](x^2+5x+6)(x+4)=x(x^2+5x+6)+4(x^2+5x+6)=x^3+5x^2+6x+4x^2+20x+24=x^3+9x^2+26x+24[/tex].
So, the answer is [tex]\boxed{a=9, b=26, c=24}[/tex]
A cubic polynomial is a type of polynomial with the degree of 3 i.e. the highest exponent of the variable is 3.
The general form of a cubic polynomial is written as p(x): ax³ + bx² + cx + d, a ≠ 0, where a, b, and c are coefficients and d is the constant with all of them being real numbers.
Given:
(x + 2)(x + 3)(x + 4)
Now, Multiplying the monomial
= (x² + 2x + 3x+ 6 ) ( x+4)
= (x² + 5x+ 6 ) ( x+4)
= x³ + 4x² + 5x² + 20x + 6x+ 24
= x³ + 9x² + 26x+ 24
Now, Comparing it with the standard form of cubic Polynomial
ax³ + bx² + cx + d
So, a= 1, b= 9, c= 26 and d= 24.

Find the equation of a line that is perpendicular to the line x=-9 and contains the point (-8,1)
Step-by-step explanation:
the line x = -9 had only one valid x value (-9), but then all values for y between -infinity and +infinity are valid.
does this sound familiar ?
it should, because the y-axis is the same type of line.
it is x = 0.
so, x = -9 is simply parallel to the y-axis.
and any line perpendicular to it (crosses the original line in a right angle = 90 degrees) is then parallel to the x-axis.
there the situation is upside-down: there is only one valid y value, and all values between -infinity and +infinity are valid x values.
since the specified point on that line has y = 1, it means that the whole line is
y = 1
solve the inequality 3x-5<10
Answer:
answer is 5
Step-by-step explanation:
am 100% sure lol
Answer:
x < 5
Step-by-step explanation:
3x - 5 < 10
[make x the subject of the formula]
3x < 10 + 5
3x < 15
[divide both sides of the equation by 3]
3x / 3 < 15 / 3
x < 15 / 3
x < 5

Step-by-step explanation:
The percentage change is computed by ...
% change = ((new value)/(old value) -1) × 100%
= (800/250 -1) × 100% = (3.2 -1) × 100%
= 220%
The increase was 220%.
please someone help me with this. Giving brainliest!!
Step-by-step explanation:
option A is correct
we will add 5 to both the sides
→ 1/8x - 5 = 3
→ 1/8x = 8
than we will multiply 8 to both the sides
→ x = 8×8 = 64.

Answer:
25/18
Step-by-step explanation:
24x - 10 = -12x + 40
<=> 24x + 12x = 40 + 10
<=> 36x = 50
<=> x = 50/36
<=> x= 25/18
