I need help what is d/7 > 15???

Answer:

yes

Step-by-step explanation:

50d^2 - 98e^2

Factor out 2.

2(25d^2 - 49e^2)

We now factor the difference of two perfect squares within the parentheses.

2(5d - 7e)(5d + 7e)

This is as far as we can factor.

Done!

The factor of the expression into an equivalent form 50d²- 98e² would be;  2(5d - 7e)(5d + 7e)

Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

We are given that expression is given that 50d²- 98e².

We have to Factorise .

Factor out 2.

2(25d² - 49e²)

We have to factor the difference of two perfect squares within the parentheses.

2(5d - 7e)(5d + 7e)

Answer:

5 inches

Step-by-step explanation:

Since the length irl is 60 yards you should divide 60 by 3.

60/3=20

Then convert 1/4 to a decimal.

1/4=0.25

Finally multiply 20 and 0.25 to get the length of the park on the map.

20x0.25=5

your answer is Option F 5 inches

Answer:

60

Step-by-step explanation:

stuffed animals = 3 x dolls eqn 1

video games = 15 + stuffed animals eqn 2

dolls = 15

replace for dolls in eqn 1

stuffed animals = 15 x 3 = 45

substitute for stuffed animals in eqn 2

45 + 15 = 60

Answer:

You have to use the Pythagorean Theorem to find the other side, which will be your base in the Area formula (A=1/2bh). So the Pythagorean theorem would be 36^2 + b^2 = 60^2. This gives you 48 in for your base/missing side length. Then, you plug it into the area formula. So, A=1/2(48) (36). This gives you 864 in^2 for the area of your triangle.

Answer:

quantities or total number of observations

Step-by-step explanation:

Average also known as mean is a measure of central tendency. It is determined by adding the numbers together and dividing it by the total number

Average = sum of the numbers / total number

For example, there are 3 numbers 3 , 6, 9

Average = ( 3 + 6 + 9) / 3 = 18 / 3 = 6
