Please help me i need it it is a true or false

Mathematics
1 answer:
Delicious77 [7]2 years ago
4 0

Answer:

False

Step-by-step explanation:

The three lengths does not make a triangle.

To see if three lengths make a triangle or not, use the formula:

a^{2}+ b^{2}= c^{2}

c^{2} is always the longest length the order of the other two numbers doesn't matter due to the associate proper of addition.

5^{2}+7^{2}  =12^{2}

25+49=144

74≠144

False

Edit:

Only use this formula if you know the triangle is a right triangle. You can also simply add the two smaller side length together to check. If the two smaller length adds up smaller or equal to the longest length, then it is false.

Factor 2a2b3 - 14ab + 16a
zhuklara [117]

Answer:

2a(b^3 - 7b + 8)

Step-by-step explanation:

I'm assuming that 2a2b3 is 2a2b^2. If not, this answer isn't correct.

Look at the whole numbers. Is there a number that divides into them evenly? Yes, 2, so you pull 2 from the problem and divide each number by 2. Do the same for each variable.

2a2b3 - 14ab + 16a

2(ab^3 - 7ab +8a)

2a(b^3 - 7b + 8)

PLEASE HELP QUICK!!!! What is the degree of 7x^6 - 6x^5 + 2x^3 + x - 8? A. 8 B. 7 C. 5 D. 6
antiseptic1488 [7]
For determining the correct degree of a polynomial, you need to look at each term and find the degree by adding the exponents of each variable in it. The largest degree is the degree of the polynomial.

7x^6 has largest degree of the given polynomial, so your answer is D.6

Find the area please
tatuchka [14]

Answer:

D

Step-by-step explanation:

Recall that the area of a triangle is given by:

\displaystyle A = \frac{1}{2} bh

In this case, the base is <em>x</em> and the height is <em>y</em>. Hence:

\displaystyle A = \frac{1}{2} xy

We can write the following ratios:

\displaystyle \sin \alpha = \frac{x}{12} \text{ and } \cos \alpha = \frac{y}{12}

Solve for <em>x</em> and <em>y</em>:

\displaystyle x = 12\sin \alpha \text{ and } y = 12\cos \alpha

Substitute:

\displaystyle A = \frac{1}{2}\left(12\sin \alpha\right)\left(12\cos \alpha\right)

And simplify. Hence:

\displaystyle A = 72\sin \alpha \cos\alpha

In conclusion, our answer is D.
