Answer:

x would be 54 degrees

Step-by-step explanation:

Since x lies on a straight line, and it gives you the other angle (126) just subtract 180 and 126.

180 - 126 = 54

29. Which of the following expressions will result in a real answer after being simplified? Select all that apply.
nexus9112 [7]

Answer: A, B, C, and E

Step-by-step explanation:

If both sides are real numbers, then the product will be a real number.

If in at least one of the sides we have a complex number, then the product will be real if:

The other number is zero.

The other number is the conjugate of the first.

This is when:

Suppose we have a number:

z = a + b*i

The conjugate will be:

w = a - b*i

And the product between them is:

(a + b*i)*(a - b*i) = a^2 + a*b*i - a*b*i + b^2 = a^2 + b^2

Then the options that will have a real answer are:

A. (4+5i)(4-5i) = 4^2 + 5^2 = 16 + 25 = 41

B. (4 + 91)*(41 - 9) = 3040

C. (3 + 2*i)*(3 -2*i) = 3^2 + 2^2 = 9 + 4 = 13

E. (312 + 7i)*(312 - 7i) = 312^2 + 7^2 = 97,393

1) What is additive inverse property?
mrs_skeptik [129]
1) additive inverse property is when an integer is added to its opposite integer (ex: -3 + 3)
2. Sorry I didn’t learn signed numbers yet :(((
3. Commutative property is when you change the order of numbers in the expression but associative property is when you are regrouping numbers in the expression.
4. Absolute value is the distance between an integer and 0. And yes you can solve distance problems and grid problems using absolute value.

How would u solve this??
Norma-Jean [14]

Answer:

n=1, m=3, and p=-4

Step-by-step explanation:

Take the fourth root of both sides

so x^n*y^m*z^p=x*y^3*z^-4;

notice z has a negative exponent because it was in the denominator

therefore, n=1, m=3, and p=-4
