Actually Welcome to the Concept of the exponents and indices.

here, we should remember one thing that,

3 ^3 = 27 and 1/3^x = 3^-x

so we get as,

(3^-3)^4-x = (3^3)^2x-1

==> 3^-12+3x = 3^6x-3

since the base is same that is 3 , we equate their powers.

-12x+3=6x-3

==> 3+3 = 6x+12x

==> 6 = 18x

hence ===> x = 6/18 = 1/3

hence, x = 1/3

Answer:

5, 10 and 11 feet.

Step-by-step explanation:

Let length of first side be x feet then

second side  = 2x feet

third side = 2x + 1 feet.

So we have the equation:

x + 2x + 2x + 1 = 26

5x + 1 = 26

5x = 25

x = 5 feet.

So first side = = 5 feet, second = 10 and third = 11 feet.

Answer:

Step-by-step explanation:

Were there not several equations from which to choose?

The coefficients of 25x^2 - 10x + 4 are {25, -10, 4}.  The discriminant is thus b^2 - 4ac, or (-10)^2 - 4(25)(4), or 100 - 400, or -300.  Because the discriminant is negative, the quadratic has no real solutions.

The quadratic equation with no real solution is 25x²-10x+4 = 0

The meaning of quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.

Given that, which of the equations have no real solution,

Considering the quadratic equation 25x²-10x+4 = 0

D = [tex]\sqrt{b^{2} -4ac}[/tex]

We know, when √D > 0, real roots

√D = 0, equal roots

√D < 0, imaginary roots

[tex]\sqrt{b^{2} -4ac}[/tex] =

[tex]\sqrt{10^{2} -400} \\\sqrt{-300}[/tex]

Since, the discriminant is less than 0, therefore, its roots are imaginary.

Hence, The quadratic equation with no real solution is 25x²-10x+4 = 0

PEMDAS

USE PEMDAS

Answer:

x = 6

Step-by-step explanation:

The triangle is a right triangle, as denoted by the red square at the bottom, we can use the Pythagorean Theorem to figure out the second side (since we are given the other side and the hypotenuse).

a² + b² = c²

(8)² + b² = (10)²

64 + b² = 100

b² = 100 - 64 = 36

b = ±[tex]\sqrt{36}[/tex]

b = ± 6

But we know that distance is always positive, so

b = 6

I have used b in place of x if you are confused about the variable usage.

Answer:

100 oz

Step-by-step explanation:

to find out how many ounces in a quarter pound, multiply 16 by ... 1/8 lb = 2 oz; 1/4 lb = 4 oz; 1/3 lb = 5.33 oz; 1/2 lb = 8 oz; 1 lb = 16 oz; 1.5 lb

Answer:

100 ounces

Step-by-step explanation:

there are 16 oz in a pound, so, 6 x 16 = 96 oz. And in 1/4 lbs there are 4 oz, so, when you add that to 96, it equals 100 oz.

D. 225 square units

Step-by-step explanation:

Multiply 2.5 by the scale factor of 6.

2.5 * 6 = 15

Then because it is a square, multiply 15*15

15 * 15 = 225

The answer is 225

Answer:

D

Step-by-step explanation:

The side length of the new square = 6 × 2.5 = 15 then its area

A = 15² = 225 units² → D

Answer:

Step-by-step explanation:

Answer:

Since by the 2nd equation, we know that y is the same as 6-x, we can substitute that for y in the first equation:

y = 2x + 3 -> 6 - x = 2x + 3 -> 6 = 3x + 3 -> 3 = 3x -< x = 1 and by either of the two equations, that derives y = 5

Step-by-step explanation:

Answer:

ok you can use subsitution for this one

since y=2x+6

subsitute 2x+6 for y

3x-(2x+6)=6

3x-2x-6=6

add like terms

x-6=6

add 6 to both sides

x=12

subsitute

y=2x+6

y=2(12)+6

y=24+6

y=30

x=12

y=30

Explanation:

2(x + 1) = 2x + 1

2(x + 1) = 2x + 1

(2)(x) + (2)(1) = 2x + 1 [Distribute]

2x + 2 − 2x = 2x + 1 − 2x

2 = 1

2 − 2 = 1 − 2
