Don't even know where to start ! xx

the perimeter is the distance around the rectangle.

the formula for that is P = 2l + 2w

so you have 25cm = 2l + 2w, y is the length so it will be 25cm = 2y + 2w

can be rewritten as 25 = 2(y + width)

divide both sides by 2, it becomes 12.5 = y + width

solve for width by subtracting y from both sides, so you get width = y-12.5cm

part b is tricky

 the formula to find the length of a side is l= (P/4)+(1/4)*squareroot(P^2-16A)

A=25, P=38 so (25/4)+(1/4)* Sqrt(25^2-16(38)) = 7.28cm

then to find length of other side use basically same formula except subtract

l= (P/4)-(1/4)*squareroot(P^2-16A) = 5.22cm

now you know the length and width of the triangle 7.28 x 5.22

so now use 7.28 as x so 2(7.28)^2-25(7.28)+76 = 0 ( this is true )

Part C  solve the equation by factoring and you should get the lengths of the sides from part b

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.
