Answer:

See below

Step-by-step explanation:

Expand L side to get

4n -12 -2n < -10 + 2n simplify L side

2n -12 < -10 +2n subtract 2n from both sides

<u>-12 < -10 </u> <===== so the equation is true for ALL n

(-∞ , + ∞ )

What is the supplementary angle of 128.7 degrees

Leno4ka [110]

Supplementary angles add to 180 so x + 128.7 = 180 subtract 128.7 from both sides; therefore, the answer is 51.3

I hope this helps!

area of a triangle is 14x^5 + 63x^2. If the base is 7x^2, write an expression to represent the height ( x^2 means x square)

mr_godi [17]

Answer:

$h=4x^3+18$

Step-by-step explanation:

Given that,

The area of a triangle, $A=14x^5 + 63x^2$

Base, $b=7x^2$

We need to find the height of the triangle.

The formula for the area of the triangle is given by :

$A=\dfrac{1}{2}\times b\times h\\\\\text{h is height}\\\\h=\dfrac{2A}{b}\\\\h=\dfrac{2\times (14x^5 + 63x^2)}{7x^2}\\\\h=\dfrac{2\times 7x^2(2x^3 + 9)}{7x^2}\\\\h=2(2x^3+9)\\\\=4x^3+18$

So, the height of the triangle is $4x^3+18$ .

Factor then solve.<br> 3x2+14x+8=0

tangare [24]

Answer:

x = - 4, x = - $\frac{2}{3}$

Step-by-step explanation:

Given

3x² + 14x + 8 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 3 + 8 = 24 and sum = + 14

The factors are + 12 and + 2

Use these factors to split the x- term

3x² + 12x + 2x + 8 = 0 ( factor the first/second and third/fourth terms )

3x(x + 4) + 2(x + 4) = 0 ← factor out (x + 4) from each term

(x + 4)(3x + 2) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = - $\frac{2}{3}$
