Answer:

a.) 12 + 5√2 - 2√6

b.) 24

Step-by-step explanation:

a) √25 + √50 - √24 + √49

  • √25 + √50 - √24 + √49

Calculate the square root .

  • 5 + √50 - √24 + 7

Simplify the radical expression.

  • 5 + 5√2 - 2√6 + 7

Combine like terms.

  • 5 + 7 + 5√2 - 2√6
  • 12 + 5√2 - 2√6

b.) √2 ( 2√8 - 3√32 + 4√50 )

  • √2 ( 2√8 - 3√32 + 4√50 )

Simplify the radical expression.

  • √2 ( 4√2 - 3 × 2²√2 + 20√2)

Evaluate the power.

  • √2 ( 4√2 - 3 × 4√2 + 20√2)

Calculate the products.

  • √2 ( 4√2 -12√2 + 20√2)

Combine like terms.

  • √2 × (4 - 12 + 20 )√2
  • √2 × 12 √ 2

Multiply.

  • 2 × 12
  • 24

Gala2k [10]

Answer:

third choice : Let 2a + 1 be one odd number, and let 2b + 1 be the other odd number. (2a + 1) + (2b + 1) = 2a + 2b + 2 = 2(a + b + 1). Because 2(a + b + 1) is evenly divisible by 2, it is an even number.

You’re welcome ;)

I need help with a math question that is 0.1x = 5/y
BabaBlast [244]
Unfortunately you have not included the directions.  Are you supposed to solve for x?  or for y?

Suppose the directions say, "Solve for x."  Then, clear out the decimal fraction by mult. both sides of the given equation by 10.  This will give you the solution, that is, a formula for x in terms of y.

What is the value of x?<br><br><br><br> Enter your answer in the box.
inna [77]

The 3 inside angles of a triangle need to equal 180 degrees.

Since you are given 2 angles, subtract both of those from 180 to find X.

X = 180 - 70 - 30 = 80 degrees.

X = 80
