Find the sum of the interior angle measures of a 4-gon.

90

Step-by-step explanation:

360/4

Hope this helps :)

Hi,

General formula is:

Sum = (n -- 2)·180°, where n is number of sides of n-gon, which n-gon must be convex.

For a 4-gon:

Sum = (4 -- 2)·180° = 360°.

Have you understood ?

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
