Step-by-step explanation:
since 4 is half of 8, you just multiply 260 by 2.
#1 is b and #2 is also b ,, i think..so sorry if i’m wrong!
<h2><u>Question</u>:-</h2>
The measurement of the three interior angles of a quadrilaterals are: 85 °, 54 ° and 96 °, what is the measurement of the fourth angle?
<h2><u>Answer</u>:-</h2>
<h3>Given:-</h3>
The measurement of the three interior angles of a quadrilaterals are: 85 °, 54 ° and 96 °
<h3>To Find:-</h3>
The measurement of the fourth angle.
<h2>Solution:-</h2>
By angle sum property of a quadrilateral,
Sum of all the interior angles = 360 °
So, let the fourth angle be x
85 ° + 54 ° + 96 ° + x = 360 °
235 ° + x = 360 °
x = 360 ° - 235 ° = 125 °
<h3>The measurement of the fourth angle is <u>1</u><u>2</u><u>5</u><u> </u><u>°</u>. [Answer]</h3>
(r*s) = (x+1)(3x+4) = 3x² + 3x + 4x + 4 = 3x² + 7x + 4
(r-s)(x) = x+1 - (3x+4) = x + 1 - 3x - 4 = -2x - 3
(r+s)(x) = x + 1 + 3x + 4 = 4x + 5
(r + s)(2) = 4(2) + 5 = 8 + 5 = 13
<h3>What is algebraic expression?</h3>
A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation. Word illustration: The product of 8 and 3. Word illustration: The product of 8 and 3 is 11

The answer would be 5/2q+9r+6r-20s
Explanation
We have the equation
5(1/2q+3r-4s)
which would equal
5/2q+15r-20s
so with the information
We can subtract 6r from 15r to get 9r
15r-6r=9r
+9r would be the missing piece
So we substitute it in to make the equation true.
5/2q(+9r)+6r-20s
Hope this helps or was correct
