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

MrMuchimi

Answer:

342,1875

Step-by-step explanation:

Dado

Precio de compra del artículo = 219

Precio de venta cuando el descuento dado es 25% = 219 + 0,25 * 219 = 273,75

Para otorgar un descuento del 25%, este producto debe estar marcado a un precio un 25% más alto que los precios de venta = 273,75 + 0,25 * 273,75 = 342,1875

F(x) = - |x| +4 Define the key features of the graph to the provided absolute value function
Kisachek [45]

Answer:

1. The minus before the |x| reflects the function in the x-axis. So it will still be V-shaped but instead but refected in the x-axis.

2. The +4 moves the function vertically 4 units upwards.

Step-by-step explanation:

We are given the function  f(x) = - |x| +4. We know that the function f(x) = |x| only has positive values, so when x>0 the function is a straight line as in the function f(x) = x. When x<0 the function is also positive, as in the function f(x) = -x. So the graph is V-shaped with the vertex at the origin.

The f(x) = - |x| +4 has two important caracteristics:

1. The minus before the |x| reflects the function in the x-axis. So it will still be V-shaped but instead but refected in the x-axis.

2. The +4 moves the function vertically 4 units upwards.

So the graph of f(x) = - |x| +4 will be V-shaped, reflected in the x-axis and moved 4 units upwards.

Attached you can find the graph

Trina planted 43 plants in her garden last week. She planted twice as many cucumbers as zucchini and eight more tomatoes than cu
Naily [24]
She planted 7 zucchini, 14 cucumbers, and 22 tomatoes.

Let z = the number of zucchini planted.  Since she planted twice as many cucumbers as zucchini, 2z is the number of cucumbers.  She planted 8 more tomatoes than cucumbers, so 2z + 8 is the number of tomatoes.  This gives us the equation

z + 2z + 2z + 8 = 43

Combining like terms, we have
5z + 8 = 43

Subtract 8 from each side:
5z + 8 - 8 = 43 - 8
5z = 35

Divide both sides by 5:
5z/5 = 35/5
z = 7

There were 7 zuccchini; 2*7 = 14 cucumbers; and 14+8=22 tomatoes.
