If its to number 9, it's ∈35.48
Just move over the two. When you change to standard form you want the x and y together and the constant by itself.
7x-4y+2=0
7x-4y+2-2=0-2
7x-4y=-2
Standard form: 7x-4y=-2

Answer: 336 cm²
Step-by-step explanation:
A trapezoid looks like a rectangle with 2 traingles attached to the side, yeah? So imagine cutting off those 2 triangles. In the middle you have a rectangle with the dimensions of 14 cm by 16 cm. The area of that rectagle is 224 cm². By subtracting the top base length from the bottom base length, you get the length of the two triangles. So, it would be 28 cm - 14 cm, giving you 14 cm. There were 2 triangles, so cut that length in half and you get 7 cm for the base of one traingle. To find the area of 1 traingle, you would do 1/2 multiplied by 7 multiplied by 16. But you have 2 triangles. so the 1/2 step isn't needed because if you put the two triangles together, you get a new rectangle. Thus, when you add the area of this new rectangle, you get 112 cm². Add this to the original rectangle, and your final area is 336 cm².
Answer:
b= 25
Step-by-step explanation:
a+b =72
a-b = 22
2a = 94
DBS(Divide Both Side) by 2
a = 47
=47 +b =72
and:
47 -b =22
subtract 47 from both sides:
b=25
and
-b = -25 MBS(Multiply Both Side) by-1 ....>b=25
