Step-by-step explanation:

2x + y = 4

Let's subtitute x = 1 for the above equation:

2(1) + y = 4

2 + y = 4

y = 2

If the area of the blue square is 144 units2 and the area of the pink square is 1225 units2, then the length of the hypotenuse i
navik [9.2K]

Answer: 37 units

Step-by-step explanation:

Blue=144units^2 This also works as the height of the triangle.

Pink=1225units^2 This also works as the base of the triangle.

Let's call pink ''a'', and blue ''b''. The side we're looking for ''c'' is the hypothenuse.

To find the values of a and b, use the area formula of a square and solve for a side. In this case, since we're going to need the squared values, this step can be omitted.

Formula: A=s^2

s=\sqrt[]{A}

Let's work with Blue.

s=\sqrt[]{144units^2} \\s=12units

Now Pink.

s=\sqrt[]{1225units^2}\\s=35units

So we have a triangle with a base of 35 units and a height of 12 units.

Now let's use the pythagoream's theorem to solve.

c^2=a^2+b^2\\c=\sqrt[]{a^2+b^2} \\c=\sqrt[]{(12units)^2+(35units)^2}\\c=\sqrt[]{144units^2+1225units^2}\\ c=\sqrt[]{1369units^2}\\ c=37units

Answer:

Here are some formulas and some info to get you started:

Step-by-step explanation:

Parallelogram:

Area = Base · Height

Triangle:

Area = 1/2 · Base · Height

Know that the height is the vertical dotted line. Also know that the horizontal dotted line attached to the base is not actually part of the base.

If you need any more help let me know, and good luck!
