Answer:

x-3=\pm\sqrt{7}

Step-by-step explanation:

We have been given an equation (x-3)^2=7. We are asked to choose the correct answer about our given equation.

To solve our given equation, we will take square root of both sides of our equation as:

\sqrt{(x-3)^2}=\pm\sqrt{7}

Using radical rule \sqrt[n]{a^n}=a, we will get:

x-3=\pm\sqrt{7}

Therefore, option B is the correct choice.

Square root both sides

we get x-3=±√7

so that would be B

1. 4x + 5y
kvv77 [185]
<h3><u>Solution</u><u> </u><u>:</u><u>-</u><u> </u></h3>

  • When x = 6 and y = 1.

1) 4x + 5y

→ 4*6 + 5*1

→ 24 +5 = 29

2) 2x (20-y)

→ 2*6 (20-1)

→ 12 *19 = 228

3) x ÷ 3 + y

→ 6 ÷ 3 + 1

→ 2 +1 = 3

4) 4y ÷ 2 + (8x + 10)

→ 4*1 ÷ 2 +(8*6+10)

→ 2 + (48+10)

→ 2 + 58

→ 60

5 ) 5. Patty made $34 baby sitting on each of 3 weekends. If she spent $50 on gifts for her family, how much money does she have left?

Money made each weekend = $34

Money made in 3 weekend = $34*3 =$102

Money spent = $50

Therefore ,

→Money left = Money made in 3 weekends - Money spent

→ Money left = $102 - $50 = $52

6.Carlos solved 20-(2x6) + 8 divide 4 = 29. Is this the correct answer? ( In attachment it's written 29 and not 28 .)

Given equation is ,

→ 20 - (2 × 6) + 8 ÷ 4 = 29

Solve inside the brackets ,

→ 20 - 12 + 8 ÷ 4

Perform division ,

→ 20 -12 + 2

Perform addition ,

→ 22 - 12

Perform subtraction,

→ 10

<u>No , he is wrong the answer should have been 10 but he got 29 .</u>

<em>I </em><em>hope</em><em> this</em><em> helps</em><em> </em><em>.</em>

Which of the following measurements could be the side lengths of a right triangle?
nataly862011 [7]

For this case we have that every rectangle traingule complies with the Pythagorean theorem:

c = \sqrt {a ^ 2 + b ^ 2}

Where:

c: It is the hypotenuse

b: It's the base

a: It's the height

It is noted that if we replace:

a = 66\\b = 88\\c = \sqrt {66 ^ 2 + 88 ^ 2}\\c = 110

So, we have c = 110 \ in ^ 2

If we evaluate the other options we will obtain wrong results.

Thus, a rectangle triangle can have measurements of:

66 in, 88 in and 110 in respectively

Answer:

Option b
