Division is repeated subtraction, just like multiplication is repeated addition. If you divide 50 by 10, you get 5. This is also the question: How many times do you have to subtract 10 from 50 to get 0?

Multiplication is said to be rapid addition. It is like adding a large group of numbers at once. This is the same with subtraction and division. Division is essentially rapid subtraction. Let me know if you need more help.

Can someone please help with this question

maksim [4K]

Answer:

X = 7.2

Step-by-step explanation:

Hello

For the triangle of right side, using Pytagoras:

(2.5)^2 + b^2 = 6^2

6.25 + b^2 = 36

b^2 = 36 - 6.25

b^2 = 29.75

b = 5.45

Now we can to find X using again Pytagoras:

3^2 + (5.45)^2 = x^2

9 + 29.75 = x^2

38.75 = x^2

X = 7.2

Best regards

Which of the following are solutions to the question below? Check all that apply.

AveGali [126]

Answer:

Step-by-step explanation:

Given

6x² - 2x + 36 = 5x² + 10x ( subtract 5x² + 10x from both sides )

x² - 12x + 36 = 0 ← in standard form

(x - 6)² = 0 ← in factored form, thus

x - 6 = 0 ⇒ x = 6 → D
