Answer:

h(- 9) = 90

Step-by-step explanation:

To calculate h(- 9) , substitute x = - 9 into h(x)

h(- 9) = (- 9)² - (- 9) = 81 + 9 = 90

M<3=(7x-10) and m<6=(5x+10)

AleksAgata [21]

Step-by-step explanation:

m∠3 = 7x - 10

m∠6 = 5x + 10

m∠3 = m∠6

7x - 10 = 5x + 10

7x - 5x = 10 + 10

2x = 20

x = 20/2 = 10°

Which term is correct when simplifying √128? A.) 16 B.) 12 C.) 10 D.) 8√2

alina1380 [7]

When dealing with roots, we want to factor to see if it's possible

$128 = 2 \times 64$
$= 2 \times 2 \times 32$
$= 2 \times 2 \times 2 \times 16$
$= 2 \times 2 \times 2 \times 2 \times 8$
$= 2 \times 2 \times 2 \times 2 \times 2 \times 4$
$= 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2$

now since we're dealing with square roots, we circle every pair of numbers we see in the final factoring
so..
$= (2 \times 2) \times (2 \times 2) \times (2 \times 2) \times 2$

now for every circled pair, we take only 1 of the 2 circled and bring it outside
anything left uncircled stays inside the root
so..
$= 2 \times 2 \times 2 \times \sqrt{2}$

now simply multiply
$8 \sqrt{2}$

HELPPPPPPP!!!! 0÷0 Find the RATIO and the EXACT VALUE of the given CscB.

AlekseyPX

Answer:

Step-by-step explanation:

take angle B as reference angle

using cosec rule

cosec B=hypotenuse/opposite

cosec B=13/12

cosec B=1.08

B=cosec 67

B=67 degree

for ratio,

cosec B=13/12

20 points helppppp which pair shows equivilent fractions

skelet666 [1.2K]

Answer:

Third

Step-by-step explanation:

First would be, simplified, 2x+10=2x-10

Second, simplified, -2x-10=2x-10

Third, simplified, -2x-10=-2x-10

Fourth, simplified, -2x+10=2x-10

So it's third :)

hope this helps :D
