Please help asap pleaseeee (picture shown)
Paraphin [41]

The correct answer is 3x+90=180

<em>Because you add the 2x and the x and you get 3x then there is a 90 degree angles so you add that and =180</em>

<em>Once you put it in the equation you can subtract 90 from 180 and you get 90 which you then divided by 3x and x equals 30</em>

Suppose B is a proper subset of C,
Tomtit [17]

Answer:

Maximum: 7

Minimum: 0

Step-by-step explanation:

A proper subset B of a set C, denoted B\subset C, is a subset that is strictly contained in C and so necessarily excludes at least one member of C.

This means that the number of elements in B must be at least 1 less than the number of elements in C. If the number of elements in C is 8, then the maximum number of elements in B can be 7.

The empty set is a proper subset of any nonempty set. Hence, the minimum number of elements in B can be 0.

Which of the following are solutions to the quadratic equation? Check all that
Troyanec [42]

Answer:

x = 1/3 or -2

Step-by-step explanation:

2x^2 + 7x - 2 = - x^2 + 2x

3x^2 + 5x - 2 = 0 (use factoring)

(3x − 1)(x + 2) = 0

3x - 1 = 0    OR     x + 2 = 0

3x = 1                   x = - 2

x = 1/3

Can you mark as brainliest? Hope it helps by the way!
