How do you simply 2x+8=-6

photoshop1234 [79]

To simplify 2x + 8 = -6, the easiest way is to manipulate the equation one step at a time:

2x + 8 = -6
2x = -14 (subtract 8 from both sides)
x = -7 (divide both sides by 2)

Step-by-step explanation:

your answer is 390

First area of the rectangle which formula is bxh base time height.

that gives you 300 since 15x20=300

The for the triangle Formula is Basexheight deivded by 2

so 15x12 devided by 2 =90

300+90=390

Hope this helps you. :)

Given a cone with a volume of 288, and height 7 in., find the base radius of the cone. Use 3.14 for pi. Round your answer to the

jek_recluse [69]

Answer:

The radius of the base is $r=6.3\ in$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

we have

$V=288\ in^{3}$

$h=7\ in$

$\pi=3.14$

substitute and solve for r

$288=\frac{1}{3}(3.14)r^{2} (7)$

$864=(3.14)r^{2} (7)$

$r^{2}=864/[(3.14)(7)]$

$r=6.3\ in$
