A. It is not possible to determine if the triangles are congruent

kirill [66]

Answer:

C. ∆ABD ≅ ∆CBD by the SSS Postulate

Step-by-step explanation:

We can prove that ∆ABD and ∆CBD congruent by the SSS Postulate.

The SSS postulate states that of three sides in one triangle are congruent to three corresponding sides in another, therefore, the two triangles are congruent.

From the diagram shown,

AB ≅ CB,

AD ≅ CD

BD = BD

We have three sides in ∆ABD that are congruent to three corresponding sides in ∆CBD.

Therefore, ∆ABD ≅ ∆CBD by the SSS Postulate

Find the product and simplify your answer. -n(-2n4+9n-5)

Harman [31]

Answer:

$+2n^5 - 9n^2 + 5n$

Step-by-step explanation:

To solve the expression

$-n(-2n^4+9n-5)$

first we will multiply -n with each term and then find their products.

When doing multiplication the powers will be added and co-efficient will be multiplied.

$-n(-2n^4+9n-5)\\-n(-2n^4) -n(+9n) -n(-5)\\+2n^5 - 9n^2 + 5n$

Angela is riding her dirt bike along a trail. She traveled 24 miles north then traveled 13 miles east. Shestopped for a moment a

Elden [556K]

The given path can be illustrated in the following diagram:

She has only 30 miles worth of gas, if she comes back through the same path then the total distance is:

$\text{Total distance=13 miles + 24 miles = 37 miles}$

Therefore, she has not enough gas to go back using the same path.

Now, the total distance traveled in a straight path (SP) can be found using the Pythagorean theorem, we get:

$\begin{gathered} SP=\sqrt[]{13^2+24^2} \\ SP=\sqrt[]{745} \\ SP=27.3\text{ miles} \end{gathered}$

Therefore, she needs to take a straight path.
