4. which algebraic expression is a polynomial with a degree of 2? 4x3 − 2x 10x2 − 8x3 3 6x2 − 6x 5

CaHeK987 [17]

ANSWER

The algebraic expression that is a polynomial with a degree of 2 is
$6 {x}^{2} - 6x + 5$

EXPLANATION

The degree of a term of a polynomial is the total sum of the exponents of the variables in each term.

The highest degree of the polynomial is considered the degree of the polynomial.

For first option,
$4 {x}^{3} - 2x + 10$
the highest degree is 3.

The second option is,
${x}^{2} - 8 {x}^{3} + 3$
This polynomial also has a degree of 3.

The third option is,
$6 {x}^{2} - 6x + 5$
This last option has a degree of 2.

Therefore the correct answer is option C.

What is the measure of angle 7?

gladu [14]

Answer: 95°

Step-by-step explanation: We are given information for Angles 1 and 4, which happen to be vertical angles, meaning they are congruent. Because of this, we can say 3x+10=4x-15, therefore x=25. Angles 1,2,3 and 4 must add up to 360°, and since we know angles 1 and 4 are 85° (3*25 + 10 = 85), we can find angles 2 and 3. 360° - 85° - 85° = Angle 2 + Angle 3. Angle 2 + Angle 3 = 190, and because Angles 2 and 3 are vertical angles and therefore congruent, we can divide 190 by 2 and get that Angles 2 and 3 equal 95°. Because lines b and c are parallel, any corresponding angles created by a transversal are congruent. This basically means Angles 3 and 7 must be congruent, therefore Angle 7 = 95°

Congruent - same meaning as equal

Vertical Angles - each of the pairs of opposite angles made by two intersecting lines.
