ivolga24 [154]

Answer:

w=V/(lh)

Step-by-step explanation:

Let

l------> the length of the base of the prism

w------> the width of the base of the prism

h------> the height of the prism

we know that

The volume of the prism is equal to

V=lwh

Solve for w

That means-------> isolate the variable w

so

Divide both sides by (lh)

V/(lh)=lwh/(lh)

Simplify

w=V/(lh)

The lenght of a rectangle is 4 cm less than three times the width. the perimeter is 64 cm
dybincka [34]
Let the width be x cm.
Then length=3x-4 cm.
Its perimeter is 64 cm.
We know that perimeter of a rectangle= 2(length+width)
So,
2(3x-4+x)=64
6x-8+2x=64
6x+2x=64+8
8x=72
x=9
Therefore,
length=(3×9-4)cm=(27-4)cm=23 cm.
Width=9 cm.

Find measurement of arc JL.
Tresset [83]
4x-2 + 7x-18 + 6x+6 = 360 degrees

combine like terms

17x-14  = 360

add 14 to both sides

17x =374

 divide both sides by 17
x = 374 / 17 = 22

JL = 7x-18
replace x with 22 and calculate
7(22) - 18 = 154 -18 = 136 degrees

Please help 10 points !!
enyata [817]

The will intersect at a point with a positive x coordinate.

We can tell this because they actually already have a shared space on the graph. If you plot the 3 points of g(x) given, you'll see that f(x) and g(x) both share the coordinate (1, 3). As a result, we know that they do intersect and it is where x (1) is a positive number.
