2√72 / √8 ± √2

If the denominator is √8 + √2,

2√72 / √8 + √2

= 2√(2*2*2*3*3) / √(2*2*2) + √2

= 2*2*3√2 / 2√2 + √2

= 12√2 / 3√2

I need help with this problem <br><br><br> -8(2v-2)=-4(7+5v)
Ne4ueva [31]

Answer: I'm not sure if this is right or not but I got U = 4

Step-by-step explanation: -8(2v-2)=-4(7+5u. So first I distributed and got -16v -16 = 28 + 20u. And then I added 16u with 20u I added because you change the sign like if it's a negative you make it a positive so once you do 20u+16v you should get 36 and then on the other side it should be -16+16 which equals -16u from when you distributed so now you should have -16u=28+36 so now you would add 28 the 36 since they both are positives and have no variables which you should get 64 and then on the left you should have 16u. So it looks like -16u=64. And then now you would divide -16u on both sides and the side with the variable put it or v whatever variable you want to use and then do 64 divided by 16 and you should get 4.

Veronda has a bag of mixed shapes. She chooses 3 shapes and fits them together to form a figure as shown. 8 cm 4 cm K 17 cm What
Ainat [17]

The area of the figure created by Verona is 96.56 cm²

<h3>Area</h3>

Area is the amount of space occupied by a two dimensional object.

The area of the circle = (1/4) * π * 4² = 12.56 cm²

The area of the square = 8 cm * 8 cm = 64 cm²

Area of the triangle = (1/2) * 8 cm * (17 - 8 - 4) = 20 cm²

Area of the figure created by Verona = 12.56 + 64 + 20 = 96.56 cm²

The area of the figure created by Verona is 96.56 cm²
