What added term would make it a monomial
Options
The given expression, has 2 variables; x and y
x has a power of 2 and y has a power of 1.
This implies that, the next term to be added must have y to the power of 1 and x to the power of 2
From the list of given options, only 2 options satisfy this condition.
When these two terms are added to , the result is a monomial.
i.e.
To find the slide we can us the pythagorical theorem that say:
![h=\sqrt[]{l^2_1+l^2_2}](https://tex.z-dn.net/?f=h%3D%5Csqrt%5B%5D%7Bl%5E2_1%2Bl%5E2_2%7D)
Where l1 and l2 iare the leg of the triangle so in our problem will be:
![\begin{gathered} h=\sqrt[]{28^2+21^2} \\ h=\sqrt[]{784+441} \\ h=\sqrt[]{1225} \\ h=35 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20h%3D%5Csqrt%5B%5D%7B28%5E2%2B21%5E2%7D%20%5C%5C%20h%3D%5Csqrt%5B%5D%7B784%2B441%7D%20%5C%5C%20h%3D%5Csqrt%5B%5D%7B1225%7D%20%5C%5C%20h%3D35%20%5Cend%7Bgathered%7D)
So the slide is 35 ft

Step-by-step explanation:
Answer:
(- 5, 0) and (3, 0)
Step-by-step explanation:
Given
f(x) = x² + 2x - 15
To find the x- intercepts let f(x) = 0, that is
x² + 2x - 15 = 0 ← in standard form
(x + 5)(x - 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5 ← left x- intercept
x - 3 = 0 ⇒ x = 3 ← right x- intercept
If a student tells me that an argument that has a false hypothesis cannot be valid, I would reply that we need to look carefully at the meaning of validity in the context of logic. In everyday speech, we tend to use “valid” to mean the same thing as “true” or “accurate.” In logic, this is not the way the term is used.
