Answer:

$x=\frac{-7+-\sqrt{37} }{6}$

Step-by-step explanation:

This (±) goes between the $-7$ and $\sqrt{37}$

$3x^{2} +7x+1=0$

$ax^{2} +bx+c$

$-b$ ± $\sqrt{b^2-4ac}$ /2a

$-7$ ± $\sqrt{(7)^2-4(3)(1)}$ /2(3)

$-7$ ± $\sqrt{49-12}$ /6

$-7$ ± $\sqrt{37}/6$

Answer:

105 feet or inches $^2$

Step-by-step explanation:

First we find the surface area of the base, (or the square.)

That is 25.

Next we find the areas of the triangle which is: $\frac{1} {2} base$ ×height

The area of one triangle is 20, so we multiply it by 4.

That is 80.

Finally, we add both surface area to find the total surface area.

That is 80 + 25 = 105

Hope that helped!

Answer:

g=6

Step-by-step explanation:

We can start by multiplying both sides by 2

5(3g+2)=100

Now we can distribute the 5 by using the distributive property

15g+10=100

Then we subtract 10 from both sides

15g=90

Divide both sides by 15

g=6
