Here's my step-by-step explanation:
Whenever you see the phrase "a number" in a problem like this, then they want you to use a variable. Let's use <em>n</em> for number and translate from English to Algebraic.
- The product of 2 more than a number and 10 is 36 more than 8 times the number.
- The product of 2 more than <em>n</em> and 10 is 36 more than 8 times <em>n.</em>
<em>- </em>The product of 2 + <em>n</em> and 10 is 36 + 8<em>n.</em>
<em>- </em>(2 + <em>n</em>)(10) is 36 + 8<em>n.</em>
<em>- </em>(2 + <em>n</em>)(10) = 36 + 8<em>n</em>
Let's solve.
(2 + <em>n</em>)(10) = 36 + 8<em>n</em>
20 + 10<em>n</em> = 36 + 8<em>n</em>
10<em>n</em> - 8<em>n</em> = 36 - 20
2<em>n</em> = 16
<em>n</em> = 8
Hope this helps, let me know if I made a mistake or if you have any questions!
Answer:
V ≈ 7850
Step-by-step explanation:
V= πr^2h is the formula
so V = 3.14 * 10^2 * 25
V = 3.14 * 2500 = 7850
depending on what decimal you use for pi, your answer will differ
Answer:
(v - 7)(v + 5)
Step-by-step explanation:
Given
v² - 2v - 35
Consider the factors of the constant term ( - 35) which sum to give the coefficient of the v- term ( - 2)
The factors are - 7 and + 5, since
- 7 × 5 = - 35 and - 7 + 5 = - 2, hence
v² - 2v - 35 = (v - 7)(v + 5)
