2 Which of the following polynomials is not written in standard form?

Varvara68 [4.7K]

Answer:

Step-by-step explanation:

Standard form is written in the order of the exponent on a variable from highest to lowest.

#1 exponents go 2, 1 , then zero. So, this is standard form.

#2 exponents go 2 then zero, so this is standard form.

#3 exponents go 1 then 2 then zero, so this is not in standard form.

#4 exponents go 3 to 2 to 1, so this is still in standard form.

hope this helps!

At a high school, students can choose between three art electives, four history electives, and five computer electives. Each stu

V125BC [204]

Answer:

$\frac{^3C_1\times ^4C_1}{^{12}C_2}$

Step-by-step explanation:

Given,

Art electives = 3,

History electives = 4,

Computer electives = 5,

Total number of electives = 3 + 4 + 5 = 12,

Since, if a student chooses an art elective and a history elective,

So, the total combination of choosing an art elective and a history elective = $^3C_1\times ^4C_1$

Also, the total combination of choosing any 2 subjects out of 12 subjects = $^{12}C_2$

Hence, the probability that a student chooses an art elective and a history elective = $\frac{\text{Total combination of choosing an art elective and a history}}{\text{ Total combination of choosing any 2 subjects}}$

$=\frac{^3C_1\times ^4C_1}{^{12}C_2}$

Which is the required expression.

If Triangle ABC is congruent to Triangle SRT, find the possible value(s) for x

Eva8 [605]

Answer:

x = 2 or x = -3

Step-by-step explanation:

Given that ∆ABC ≅ ∆SRT, it follows that their corresponding side lengths are congruent to each other.

Thus:

$RT = BC$

$(x^2 + x) = 6$

Solve for x

$x^2 + x = 6$

Subtract 6 from each side

$x^2 + x - 6 = 6 - 6$

$x^2 + x - 6 = 0$

Factorise

$x^2 + 3x - 2x - 6 = 0$

$x(x + 3) -2(x + 3)$

$(x - 2)(x + 3)$

x = 2 or x = -3
