I DO NOT UNDERSTAND SOMEONE PLEASE HELP

Mathematics
1 answer:
sammy [17]3 years ago
8 0

Answer:

a = 12cm

Third option

Step-by-step explanation:

Use the pythagorean theorem because this is a right triangle and you are looking for a missing side.

The formula is:

a² + b² = c², where "a" and "b" are sides, but "c" is the hypotenuse (longest side).

We know the hypotenuse and one other side.

Substitute side "b" and "c".

a² + 5² = 13²

a² + 25 = 169   Isolate "a"

a² = 169 - 25    Subtract 25 from both sides

a² = 144         Find the square root of both sides

a = √144

a = 12

The mssing side, "a", is 12 cm long.

4/x³ - (2x-1)/3x

= (4*3) - (2x-1)(x²) / 3x³

= (12 - 2x³ - x²) / 3x³

= -2x³ -x² + 12 / 3x³

The answer is C.

May I please receive help
mafiozo [28]

Hello mate ☺️,

We know that m < 2 = 96°, as,

m < 5 = 96°(Alternate angles are equal)

Now we know that m < 5 = 96°, so,

→ m < 5 + m < 8 = 180°(Linear Pair angles are supplementary)

→ 96° + m < 8 = 180°

→ m < 8 = (180 - 96)°

→ m < 8 = 84°

Therefore, <u>m<5 = 96°</u> & <u>m<8=84°</u>

✍️ <em>By </em><em>Benjemin</em> ☺️

Enter the equation of the line in the form y=mx where m is the slope.Immersive Reader
kari74 [83]

Answer:

y = 1/2x

Step-by-step explanation:

The slope is the rise (up) over run (left or right depending on if the number is negative) between points. So the next point on the graph is up 5 and over 10. this simplified is 1/2. Then you put this into y=mx which is y=1/2x

djverab [1.8K]
6x>-25 and 9x<54the answer (solve x ) you have 6x>-25 so we solve 'x' we say divide by 6 both side then we get { x>-25/6 or x>-4.166} second you have 9x<54 we say divide by 9 each side { x<6 } your answer is { x>-25/6 and x<6 }
