Mathematics

5 0

Answer:

No

Step-by-step explanation:

8−2x<12

Subtract 2 from each side

8-8−2x<12-8

-2x <4

Divide each side by -2, remembering to flip the inequality

-2x/-2 >4/-2

x > -2

Is -2 a solution

-2 >-2

This is false, it is equal

HELP ME ASAP! Will give BRAINLIEST! Please read the question THEN answer correctly! No guessing. Check ALL that apply.
Elena L [17]

Answer:

x = -2 or x = 1/3 thus: B & C

Step-by-step explanation:

Solve for x over the real numbers:

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

Subtract 2 x - x^2 from both sides:

3 x^2 + 5 x - 2 = 0

The left hand side factors into a product with two terms:

(x + 2) (3 x - 1) = 0

Split into two equations:

x + 2 = 0 or 3 x - 1 = 0

Subtract 2 from both sides:

x = -2 or 3 x - 1 = 0

Add 1 to both sides:

x = -2 or 3 x = 1

Divide both sides by 3:

Answer: x = -2 or x = 1/3

I need help!! It’s proving trapezoids theorems
sweet [91]

Because ABCD is an isosceles trapezoid, the angles A and D are congruent.

BA and CD are congruent (given) and AD is congruent to itself (reflexive property).

Then triangles BAD and CDA form a pair of SAS triangles, so they are congruent.

BD and CA are corresponding parts in those triangles, so they are congruent (CPCTC).
