1 answer:
MakcuM [25]3 years ago

Answer:

-49

Step-by-step explanation:

Make sure you understand the difference between

-3² and (-3)²

-3² means square 3, then take its opposite. -3² is the same as -(3²) = -9

(-3)² means square the number -3, which means that (-3)² = (-3) × (-3) = 9

Ok, now we can start. Use the correct order of operations.

-3² + (2 - 6)(10) =

= -9 + (-4)(10)

= -9 + (-40)

= -9 - 40

= -49

VMariaS [17]

Step-by-step explanation:

<h3>★ Solution:-</h3>

\sf \leadsto \dfrac{7x - 3}{5x - 2} = -2

\sf \leadsto 7x - 3 = -2(5x - 2)

\sf \leadsto 7x - 3 = -10x + 4

\sf \leadsto 7x + 10x = 4 + 3

Simplify the following expression 2/5 + 4/3 over 3/5
madreJ [45]
This written out is:

2/5 + 4/3
------------
     3/5

Roughly, now first we need to change the denominators to all match up in order to properly solve this problem.

Both 5 and 3 go into 15, 5 goes into 15 3 times and 3 goes into 15 5 times. With that said, multiply the individual numerators by 5 and 3.

2/5 -> 2*3/15 -> 6/15
4/3 -> 4*5/15 -> 20/15
3/5 -> 3*3/15 -> 9/15

With this, we then add the top numerator of the overall problem:

26/15
------- | With this we now cross-multiply.
 9/15

26/15 * 15/9 = 390/135 | Now to simplify this.

135 goes into 390 twice, as 270. Subtract 390 by 270, leaving us with 120.

Meaning: 2 120/135 is the answer, but now to simplify. Divide 120 and 135 by 5 to lessen this.

24/27 | Divide this by 3 to get your most simplified answer.
8/9 | Leaving us with the answer of:

2 8/9

I hope this helps, have a great rest of your day! ^ ^

Dada

larga l=20\ m

superficie A=280\ m^2

Suponga que el ancho es w

La superficie está dada por el producto de la longitud y la anchura.

\therefore A=lw\\\Rightarrow 280=20\times w\\\Rightarrow w=14\ m

Por lo tanto, el ancho es de 14 m.
