If the side of square P is x and the side of square Q is y, we have x+y=26. In addition, 3*the perimeter of P+8*4y=3*4x+32y=12x+32y=492.
We have
x+y=26
12x+32y=492
Multiplying the first equation by -12 and adding it to the second, we get
20y=180 and dividing by 20 we get y=9. Plugging it into the first equation, we get 26-9=17=x. Since the area of square P is x^2 and Q is y^2,
x^2+y^2=19^2+7^2=410=the sum of the squares
Answer:
10
The 3rd option , C.
100 - 80 = 20
80 = 72
20 = ?
72 / 80 = 0.9
20 x 0.9 = 180
180 + 72 = 252
Answer:
10 gallons
Step-by-step explanation:
Area of one rectanglular side
10 * 44 = 440
Area of trangular one triangular "roof"
(1/2)10 * 9 = 45
Total area = 4(440 + 45) = 1,940

Paint needed
1940 / 202 = 9.6

Answer:
<h2>First quadrant will the line not pass.</h2>
Step-by-step explanation:
The given line has a negative slope. It means with increasing value of x, y will be decreasing. It has a negative y-intercept that is at x = 0, y is less than 0.
If the value of x will be greater than 0, the value of y will be going downwards continuously.
If x > 0, y < 0, as the line has a negative y-intercept.
A point in first quadrant means x > 0 as well as y > 0.
Hence, the line cannot pass through the first quadrant.
