Write down the degree of given polynomial 5x⁴+4x²+2x+1

shusha [124]

Answer:

4

Step-by-step explanation:

To find the degree of a polynomial, identify the term with the greatest exponent. The exponent of that term is the degree of the polynomial.

In the given polynomial 5x⁴+4x²+2x+1, the term with the greatest exponent is 5x⁴. This term has an exponent of 4, so therefore, the degree of the polynomial is 4.

I hope this helps!

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 p

nikklg [1K]

X = large boxes and y = small boxes

x + y = 70.....x = 70 - y
60x + 65y = 4300

60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs

x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs

Which expressions are equivalent to 5p+3p+(-9)5p+3p+(−9)5, p, plus, 3, p, plus, (, minus, 9, )? Choose all answers that apply:

Lemur [1.5K]

Answer:

Option B.

Step-by-step explanation:

The given expression is

$5p+3p+(-9)$

We need to find an expression which is equivalent to the given expression.

Combine like terms.

$(5p+3p)-9$

$8p-9$

The simplified form of given expression is 8p-9. So, option A is incorrect.

In option B, the given expression

$3(p+(-3))+5p$

$3(p-3)+5p$

Using distributive property, we get

$3p-9+5p$

Combined liker terms.

$(5p+3p)-9$

$8p-9$

It is same as the simplified form of given expression.

Therefore, the expression 3(p+(-3))+5p is equivalent to the given expression and correct option is B.
