Answer:

m is equal to -1 ± 2√3, which is approximately equal to 2.46 and -4.46

Step-by-step explanation:

-4m² + 2m - 11 = -5m²

m² + 2m - 11 = 0

m² + 2m + 1 = 12

(m + 1)² = 12

m + 1 = ± √12

m = -1 ± 2√3

Step-by-step explanation:

This problem can take a while if you cannot observer the answer quickly.

First of all we can see that 32=2*2*2*2*2=2^5

243, if you don't know its actually is 3^5

Now we can see that this turns into...

- 2^5/3^5

since the 5th power doesn't change the sign of the original number, we can put the negative in the ( ), if you don't know what I mean look below

(-3)^2=9 Positive

(-3)^3=-27 Negative since its to the odd power it keeps the sign.

This problem can be simplified to.

(-2/3)^5

And this is the answer :D

Answer:

The surface area is 286.5in.

Step-by-step explanation:

7.5 * 11.5 = 86.25 * 2 = 172.5in for two big rectangles

7.5 * 3 = 22.5 for little rectangle

11.5 * 3 = 34.5 * 2 = 69 for two medioum rectangles

7.5 * 3 = 22.5 for the smallest rectangle

22.5 + 69 + 22.5 + 172.5 = 286.5 in SA

Answer: D

Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.

Answer:

65.97m³

Step-by-step explanation:

This is a right circular cone, so we will be using V = (1/3)(π)(r²)h

r = radius = 3m

h = height = 7m

V = (1/3)(π)(3m²)(7m) = 65.97m³

The bracket means to multiply.

Answer:

HOPE I HELPED:)

Step-by-step explanation:

Answer: 14

Step-by-step explanation:

110 + 110 + 70 + 5x= 360 ( total number of angles in a quadrilateral is 360 degrees)

290+5x= 360

5x= 360 - 290= 70

x= 70/5= 14

Step-by-step explanation:

9514 1404 393

Answer:

  a, b

Step-by-step explanation:

This has to do with correctly using the distributive property to distribute a negative multiplier.

a) (5p -7) -(3p +1) = 5p -7 -3p -1 = (5-3)p +(-7-1) = 2p -8 . . . . true

__

b) (10b +3) -(-2b +78) = 10b +3 +2b -78 = (10+2)b +(3 -78) = 12b -75 . . . . true

__

c) (4h +2) -(h -6) = 4h +2 -h +6 = (4-1)h +(2+6) = 3h +8 . . . . not 3h-4 (false)

so it's a square which means all of the sides are equal.

that means x+7=3x+1

      subtract 1 from both sides

x + 6 = 3x

      subtract x from both sides

6 = 2x

      divide both sides by 2

3 = x

you can do the same for y

2y - 1 = -3y + 14

    add 3y to both sides

5y - 1 = 14

     add 1 to both sides

5y = 15

      divide both sides by 5

y = 3

Answer:

Susan's dog weighs 9.75 pounds

Step-by-step explanation:

Given

The weight of Susan's cat = 3 pounds

Susan's dog weighs 3 1/4 or 13/4 times as much as her cat.

To determine

The weight of Susan's dog = ?

As the weight of Susan's cat = 3 pounds

Given that Susan's dog weighs 3 1/4 or 13/4 times as much as her cat. so

The weight of Susan's dog = 13/4 of 3

                                             = 13/4 × 3

                                              = 39/4

                                               = 9.75 pounds

Therefore, Susan's dog weighs 9.75 pounds

Answer: m∠E = 55°

Step-by-step explanation: If a triangle has two equal sides, it is called Isosceles. Another characteristics of this type of triangle is that the angles opposite the equal sides are also congruent.

Triangle ΔEFG has two sides with approximately the same length:

[tex]\overline{GE}[/tex] ≈ [tex]\overline{FG}[/tex]

So, it is an isosceles.

Therefore the opposite angles are m∠E and m∠F.

m∠E = m∠F

m∠E = 55°

Angle at vertex E is 55°.
