4(3x+5)= -4

NeX [460]

Answer/explanation

4(3x+5)=-4

You will distribute the four to every term in the parenthesis,

12x+20=-4

Then you will combine like terms

12x+20=-4

-20 -20

12x=-24

Then you will divide 12 to isolate x

$\frac{12x}{-24} =\frac{-24}{-24}$

Obviously, -24 cancels out and you would get x=-2

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 $4x^3+18$ .

724.94 I THINK.
787.00+135.46=922.46

Pls Help. If you do I will give the first person who answers 100 points

Vikki [24]

Answer:

Step-by-step explanation:

so the point $(\sqrt{3},\sqrt{7})$ is in the circumference so the distance from (0,0) to this point will be the radius of the bullseye

$x=\sqrt{(\sqrt{3}-0)^2+(\sqrt{7}-0)^2}\\\\x=\sqrt{3+7}\\\\x=\sqrt{10}$

so that's the radius

so the area will be

$A=\pi x^2\\\\A=\pi (\sqrt{10})^2\\\\A=10\pi$

so the percentage is

$P=\frac{A}{1600}\\\\=\frac{10\pi}{1600}\\\\=\frac{\pi}{160}\\\\P\approx 0.02$

so it's 2%
