Answer 1
Answer: The answer is A, because:
The dimentions in cm are 5cm by 3cm, so you make that to scale. The page says that 1cm is equal to 5m, so you multiply both numbers by 5 and you get 25 by 15. If you need clarification, let me know.
Answer 2
Answer: The answer is a because to get the length of the sides you do 7-4 which is 3 times five is 15m. To find the base you do 2 times 3 times 5 which is 25m. A) 25m. * 5m.

Which represents the polynomial below written in standard form

Answers

Answer:

(1/2)(8x³ + x² - 6x + 12)

Step-by-step explanation:

Next time, please share the possible answer choices.  Thanks.

Multiplying all four terms of the given polynomial by 2 results in

x² - 6x + 8x³ + 12

Rearranging these terms in descending order by powers of x:

(1/2)(8x³ + x² - 6x + 12)

Note that we cannot just ignore that '2' in the denominator, because the given polynomial is an expression, not an equation.

Jessica is making 2 loaves of banana bread. She needs 3/4 cup of sugar for each loaf. Her measuring cup can only hold 1/4 cup of sugar. How many times will Jessica need to fill the measuring cup in order to get enough sugar for both loaves of bread?

Answers

3/4*2
=6/4
6/4/1/4
=6/4*4
=6
so 6 pours

Answer:

6 times


Explanation:

1- getting the number of times required for one loaf:

We know that:

The loaf requires 0.75 of a cup of sugar

The cup can hold 0.25 cup of sugar

To know the number of times required to get the needed amount, we will simply do cross multiplication as follows:

1 time ................> 0.25 of a cup

?? times ..........> 0.75 of a cup

Number of times for one loaf = (0.75*1)/(0.25) = 3 times


2- getting the number of times required for two loaves:

We have calculated that one loaf requires filling the measuring cup 3 times, this means that:

2 loaves would require filling the cup 2*3 = 6 times


Hope this helps :)
