Answer:

False

Step-by-step explanation:

To find out if you can form a triangle from the measurements, you can compare the numbers.

If you add any combination of these number together, they need to be greater than the one you're comparing to.

3 + 5 needs to be greater than 9.

But it's not.

The other combinations work:

3 + 9 > 5

9 + 5 > 3

But since the first combination didn't work, these measurements will not form a triangle.

Hope I helped :)

(I know this answer is 3 years late but I just took the test and got it right.)

False, No Triangle can be formed with those side lengths. Here's why:
The sum of side a and side a has to be greater than side c.
a+b>c
3+5= 8
8 is not greater than 9

Tju [1.3M]

Answer:

$\log(150)$

Step-by-step explanation:

We want to rewrite the following as a single logarithm:

$2 - log(6) - log(9)$

We introduce logarithm in the first term to get:

$2 \log(10) - \log(6) - \log(9)$

Recall that:

$log(a) - log(b) = \log \frac{a}{b}$

We apply this property to get:

$2 log(10) - log( \frac{6}{9} )$

This gives:

$log( {10}^{2} ) - log( \frac{6}{9} )$

$log( {100}) - log( \frac{2}{3} )$

$log( \frac{100}{ \frac{2}{3} } ) = log( \frac{300}{2} ) = log(150)$

Answer:

Straight

Step-by-step explanation:

If the angle is flat or 180 degrees, it is straight

If the angle is like an L or 90 degrees, it is right

If the angle is less than 90 degrees, it is acute

If the angle is more than 90 degrees, it is obtuse

Pachacha [2.7K]

Answer:

1) 4/10

2) 2/8 and 4/16

3) $13,592

4) 216 cards

5) 6 stickers

6) Subtract 2 then add 3

Step-by-step explanation:

1) Since the fraction is already reduced, multiply top and bottom by a positive integer bigger than 1

2) Same as number 1

3) Multiply 1,699 by 8, 1699*8=13592

4) Multiply 18 by 12, 18*12=216

5) Find the remainder after dividing 41 by 7

6) 8 subtract 2 is 6, add 3 is 9, subtract 2 is 7, add 3 is 10, and so on…
