First add 2 2/4 and 1 3/4
= 4 1/4
Then subtract 4 1/4 from 12
= 7 3/4
Answer:
Step-by-step explanation:
To find the number of yard, <em><u> divide </u></em> the number of feet by the unit rate <em><u> 3 </u></em> feet per yard.
The answer is x=65.
The step by step explanation is on the paper.
1) The given expression 7x^4 + 5x^2 + x - 9 is a polynomial.
2) The given expression 7x^6 - 4x^3 + 1/x is a trinomial.
<u>Step-by-step explanation</u>:
1) 7x^4 + 5x^2 + x - 9
- The number of terms in the above expression is 4.
- An algebraic expression with more than 3 terms is known as polynomial.
- <u>The degree is the power of the x term in a expression</u>
- first term = 7x^4 has a degree of 4.
- second term = 5x^2 has a degree of 2.
- third term = x has a degree of 1.
- fourth term = 9 is a constant term with no degree.
2) 7x^6 - 4x - 1/x
- The number of terms in the above expression is 3.
- An algebraic expression with 3 terms is known as trinomial.
- first term = 7x^6 has a degree of 6.
- second term = 4x has a degree of 1.
- third term = 1/x has a degree of -1.
Answer:
20
Step-by-step explanation:
We know that ΔBAC and ΔBED are similar becuase of the AA Postulate (they both have a right angle and they both share ∠B). Since AC is 15/3 = 5 times longer than ED, the scale factor is 5 which means AB is 5 times longer than EB. This makes EB = 25 / 5 = 5. Since AB = AE + EB and we know that AB = 25, AE = x and EB = 5, 25 = x + 5 which means x = 20.
