W is 21/4+5/6 that is equal 73/12
Rectangle- multiply it’s height by width
Square- you need to find the length of one of the sides and then multiply this by itself to find the area.
Nearest hundred thousand is 400,000
Answer:
137
Step-by-step explanation:
Sum of opposite angles in a quadrilateral embedded in a circle = 180
43+x=180
x=180-43
x=137
The expression which can be used to determine the algebraic sum of the given polynomials as in the task content is; -11x² +4x +14.
<h3>Which expression can be used to find the sum of the given polynomials?</h3>
It follows from the task content that the polynomials whose sum are to be determined are; (9 - 3x2) + (-8x2 + 4x + 5).
Hence, the sum can be evaluated as follows;
= 9 - 3x² + -8x² + 4x + 5
= -11x² +4x +14.
Consequently, the required expression is; -11x² +4x +14.
