Answer:

A) −20

Step-by-step explanation:

−5/3 (−2/3 )(−18)

Multiply the first and second terms. A negative times a negative is a positive

-5/3 * -2/3 = 10/9

10/9 * -18

Rewriting for easier math

-18/9 * 10

-2 * 10

-20

(-1, -30) a solution of y = 10x? a) True b) False

Travka [436]

~Psst, hey kid~

I believe the answer is false, because y = 10x means the x, (1) is being multiplied by 10, also it's a negative, and 10x is a positive equation.

Hope this helped...

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 $4x^3+18$ .
