Answer

Given expression,

(81x^2-25)\times \dfrac{6}{18x+10}

We have to find the value of x for which the expression is undefined.

Simplifying the given expression

((9x)^2-5^2)\times \dfrac{3}{9x+5}

(9x-5)(9x+5)\times \dfrac{3}{9x+5}

3(9x-5)

On solving we can see that the expression is defined for all value of x.

Klio2033 [76]

Answer:

she can buy 12½flip flops

Step-by-step explanation:

it's actually easy : just do 50÷4 but then u will get something like 12.5 so if you are confused , you can divide by the closest number to 50 and the number which is a multiple of 4

so,

48÷4 = 12 and with the remaining 2 $ she can buy a half flip flop more if she wants because 4/2

Therefore , the total number of flip flops she can buy = 12½ flip flops

Find the measure of each interior angle AND each exterior angles of the following regular polygons. Show your work.
fredd [130]
<h3>Given</h3>

regular polygons with 5, 16, and 12 sides

<h3>Find</h3>

the measures of each interior and exterior angle

<h3>Solution</h3>

The sum of exterior angles is 360° for any convex polygon. For a regular n-agon, the measure of an exterior angle is 360°/n. The corresponding interior angle is its supplement.

(a) pentagon. Exterior angle: 72°; Interior angle: 108°.

(b) 16-gon. Exterior angle: 22.5°; Interior angle: 157.5°.

(c) dodecagon. Exterior angle: 30°; Interior angle: 150°.
