what are the measures of angles a, b, and c? show your work and explain your answers.

two straight lines intersect at a point to form angle a. the measure of the angle opposite to angle a is 35 degrees. angle a is the angle of a right triangle having another angle equal to b. a triangle with one angle labeled c is on the left of the figure. the angle adjacent to c is labeled 70 degrees.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
