Answer:
106 m²
Step-by-step explanation:
we can see in the figure that it is made up of one square and one trapezium
Formula to calculate the area of this polygon
Area of square + Area of trapezium
Area of square
side²
5²
25
Area of trapezium
<em>here a and b is the parallel sides</em>
<em> h is the height of trapezium </em>
(6+3)(9)
(9)(9)
81
Area of the polygon
25 + 81
106

Answer: 76 </h3>
=======================================================
Explanation:
Replace x with 4 and y with 5.
Then use the order of operations (PEMDAS) to simplify until you get a single number.
Something like 9x means "9 times x", and a similar situation happens with the 8y term as well.
---------
Here's what the steps look like:
9x + 8y
9*4 + 8*5
36 + 40
76
Therefore, 9x+8y = 76 when x = 4 and y = 5.
The point (4,5) is located on the line 9x+8y = 76
Answer:
x = 2, y = 6
Step-by-step explanation:
Δ WXY is equilateral ( 3 congruent angles ), then the sides are equal
WY = WX , that is
y - 1 = 5 ( add 1 to both sides )
y = 6
Δ WYZ is isosceles ( 2 congruent base angles ) then the legs are congruent
YZ = WY , that is
x + 3 = 5 ( subtract 3 from both sides )
x = 2
Answer:
11 x ^2 + x + 6.
Good luck & have a good day!
