Answer:

77+24\sqrt{10} m²

Step-by-step explanation:

Since it is a square, the side lengths are the same. Multiply the side lengths by each other to find the area.

(4\sqrt{2}+3\sqrt{5})(4\sqrt{2}+3\sqrt{5})

= 32+12\sqrt{10}+12\sqrt{10}+45

= 77+24\sqrt{10} m²

3x + 5y = 7<br> How to solve it
Lubov Fominskaja [6]

Answer:

x=1 and y=4/5

Step-by-step explanation:

<u>Given system of equations</u>

3x+5y=7

5x+10y=13

<u />

<u>Multiply first equation by 2</u>

2(3x+5y)=2(7)

6x+10y=14

<u>Eliminate y-variable to get "x"</u>

 6x+10y=14

<u>- 5x+10y=13</u>

         x = 1

<u>Substitute x=1 into either equation and find "y"</u>

3x+5y=7

3(1)+5y=7

3+5y=7

5y=4

y=4/5

Therefore, x=1 and y=4/5

Which quadratic function has a wider graph than y=2x^2?
Trava [24]

Answer:

y = 1/2 x²

Step-by-step explanation:

The coefficient of the first term in a quadratic, in our case here, x², will tell us how the graph stretches. This is akin to the slope within the linear graph. Similar to the slope, the smaller the coefficient value, or value of slope m, the shallower the angle.

When discussing quadratics, the larger the coefficient of our x² term, the steeper, and skinnier the graph. If we want to look for a graph that is wider than y = 2x², then we need to find a graph with a coefficient that is less than 2.

Our only option then is

y = 1/2 x²
