Vicky made some purchases at the
ELEN [110]

Step-by-step explanation:

Vicky Bought:

Strawberries $3.50

Carrots $2.25

Flowers $9.95

Subtotal $3.50 + $2.25 + $9.95

= $15.70

5% Sales Tax (5% of Subtotal) = 5/100 x $15.70

= $0.785 (will not round off here as it is not the final answer.)

Total = Subtotal + 5% Sales Tax

= $15.70 + $0.785

= $16.485

= $16.49 (rounded off to nearest cent)

Which expression is equivalent to n2 26n 88 for all values of n? (n 8)(n 11) (n 4)(n 22) (n 4)(n 24) (n 8)(n 18)
Sunny_sXe [5.5K]

The factor of the given polynomial n² + 26n + 88 is (n + 4) and (n + 22). Then the correct option is B.

<h3>What is a factorization?</h3>

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The polynomial is given below.

n² + 26n + 88

Then the factor of the given polynomial will be

n² + 22n + 4n + 88

n(n + 22) 4(n + 22)

(n + 4)(n + 22)

More about the factorization link is given below.

If &lt; 1 mesures 65°, what does &lt;3 measure?
kakasveta [241]

When you have one measure , you can find any measure

1 measure = 65

So, you times (×) it by the number three (3) and you'll get 195 degrees.

You can do it by any number once you find one measure or share.
