Answer:

Therefore,

l(AB) = 15 units

Step-by-step explanation:

Given:

AD = DC

angle DBA = angle DBC = 90°

AB = 5x

CB = 4x - 3

To Find:

AB = ?

Solution:

In  Δ ABD and Δ CBD

AD ≅ DC     ……….{Given}

∠ DBA ≅ ∠ DBC      …………..{measure of each angle is 90° given}

DB ≅ DB                  ....……….{ Reflexive property}

Δ ABD ≅ Δ CBD      ..........….{By Hypotenuse Leg Theorem}

∴ AB ≅ CB               ..............{corresponding sides of congruent triangles}

on substituting the values we get

5x=4x+3\\\\5x-4x=3\\\\\therefore x =3

Now we require AB

AB=5x\\\\AB=5\times 3\\\\AB=15\ units

Therefore,

l(AB) = 15 units

The length of a rectangle is 6 meters more than its width. If the area is 135 square meters, what is its width?
Novay_Z [31]
Length = width +6

L * (L - 6) = 135

L^2 - 6L = 135

L^2 - 6L -135 = 0

Length = 15
Width = 9

A small cruising ship that can hold up to 66 people provides three-day excursions to groups of 42 or more. If the group contains
lana66690 [7]
<h3>Answer:</h3>

50 people

<h3>Step-by-step explanation:</h3>

Let x represent the number of people on the cruise. The amount they each must pay is ...

... ($58 -(x -42)) = $100 -x

The revenue from the group is the product of the number of people and the amount each pays:

... r(x) = x·(100 -x)

This describes a downward-opeing parabola with zeros at x=0 and x=100. The vertex (maximum) will be found halfway between those zeros, at x=50.

A group size of 50 maximizes revenue from the cruise.
