Write the polynomial in standard form. then choose the name of the polynomial based on its degree and number of terms.
-5+ x² + x
a x + x2 - 5; cubic trinomial
b. -5 + x2 + x3; cubic trinomial
c. x + x2 - 5. quadratic trinomial
d. -5 + x2 + xo: quadratic trinomial

C. x + x² - 5. quadratic trinomial

Step-by-step explanation:

The expression -5+ x² + x is already simplified so we only need to rearrange the terms.

The standard form for a quadratic equation is ax² + bx +c. We knowits quadratic because of "x²".

-5+ x² + x   =>   x² + x - 5

The degree is 2 because the degree of an equation is the greatest exponent on the variable(s) in one of the terms.

Between x², x and -5, x² has the greatest exponent of 2.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
