We know a rectangle has 4 sides, 2 longer and 2 shorter. If one side is 35 cm, then we know that another side is also 35cm. So, the lengths of 2 of the sides are 70 cm together. We have 14 cm left. Divide 14 by 2. The other 2 sides are 7 cm wide.

Perimeter is 2 length + 2 width so 84=2(35) + 2(width)

Find the slopes of the asymptotes of the hyperbola with the following equation.
frosja888 [35]
You are given the equation 36 = 9x² + 4y². You are asked to find the slopes of the asymptotes of the hyperbola. A hyperbola has the following general equation x²/a² + y²/b² = 1. the goal here is to find the slopes of the hyperbolic equation. So divide both sides by 36

36 = 9x² + 4y²
(1/36)[36 = 9x² + 4y²]
1 = x²/4 + y²/9
a² = 4
a = 2
and
b² = 9
b = 3

To find the slope, divide a/b and you will get 2/3.

Two tanks hold a total of 55 gallons of a toxic solvent. One tank holds 4 gallons more than twice the amount in the other. How m
Serhud [2]

Step-by-step explanation:

If x is the volume of the first tank, and y is the volume of the second tank, then:

x + y = 55

x = 2y + 4

Solve the system of equations using either substitution or elimination.  Using substitution:

2y + 4 + y = 55

3y + 4 = 55

3y = 51

y = 17

Solve for x using either equation.

x + 17 = 55

x = 38

The first tank holds 38 gallons, and the second tank holds 17 gallons.

Clara has a garden that is 7 feet wide and 4 feet long she has 30 tomato plants to put in the garden each plant needs one square
ankoles [38]
A = L * W
A = 7 * 4
A = 28 sq ft....this is the area of her garden

and if each plant uses 1 sq ft, then there will be (30 - 28) = 2 plants leftover
