(06.01 MC)

What is the value of the expression 9 − (fraction 1 over 2)4 ⋅ 48?

D. 9

the answer is 8.9375,but the answer provided in whole number.You just need to round off to tge nearest whole number.

Question 7(Multiple Choice Worth 1 points)
(06.02 LC)

Which statement best describes the expression 2y ÷ 7?

A. 2 times y divided by 7

B,C and D are obviously wrong.It doesn't related on the equation given.A is the right answer

Question 8(Multiple Choice Worth 1 points)
(06.02 MC)

Which of these is the algebraic expression for "4 less than the product of 5 and some number?"

The work of a student to find the dimensions of a rectangle of area 8 + 16x and width 4 is shown below:

A. Step 1: 8 + 16x
B. Step 2: 4(4) + 4(12x)
C. Step 3: 4(4 + 12x)
D. Step 4: Dimensions of the rectangle are 4 and 4 + 12x

In which step did the student first make an error and what is the correct step?

C. Step 2; 4(2) + 4(4x)

The first error is at the step 2.It doesn't show the right solution.4(4x),not 4(12x).That is obviously wrong.How could 16 can be 12 even the expression not multiply by any number yet ! that obviously WRONG. C is the right answer

nika2105 [10]

Answer:

For -2x^2+x, Leading coefficient is -2, Degree is 2, Constant term is 0

For 9-25x^2+8x, Leading coefficient is -25, Degree is 2, Constant term is 9

For x^5+x^3-x^2-1, Leading coefficient is 1, Degree is 5, Constant term is -1

Step-by-step explanation:

Given:

Polynomials:

-2x^2+x\\9-25x^2+8x\\x^5+x^3-x^2-1

To find: leading coefficient, constant term and degree

Solution:

Leading coefficient is the coefficient of the variable with the highest power.

Degree is the highest power of the variable.

The term of degree 0 is the constant term of a polynomial.

For -2x^2+x,

Leading coefficient is -2

Degree is 2

Constant term is 0

For 9-25x^2+8x

Leading coefficient is -25

Degree is 2

Constant term is 9

For x^5+x^3-x^2-1

Leading coefficient is 1

Degree is 5

Constant term is -1
