Answer:

13 = x

Step-by-step explanation:

[tex]\frac{6}{8}[/tex] = [tex]\frac{(x + 2)}{(x + 7)}[/tex]

6x + 42 = 8x + 16

42 = 2x + 16

[tex]\frac{26}{2}[/tex] = [tex]\frac{2x}{2}[/tex]

13 = x

Find the square root of 25x^2-40xy+16y^2​

Answers

The square root of [tex]25x^2-40xy+16y^2[/tex] is 5x - 4y.

Given that,

The quadratic equation is [tex]25x^2-40xy+16y^2[/tex].We need to find out the square root.

Based on the above information, the calculation is as follows:

[tex]= 25x^2-40xy+16y^2\\\\= (5x)^2 - (2\times 5x \times 4y) + (4y)^2\\\\= (5x - 4y)^2\\\\= \sqrt{ (5x - 4y)^2}[/tex]

= 5x - 4y

Therefore we can conclude that the square root of [tex]25x^2-40xy+16y^2[/tex] is 5x - 4y.

Answers

Answer:

x=-18

Step-by-step explanation:

Answer:

The answer is -18

Step-by-step explanation:

STEP 1:

[tex]3 \times \frac{2}{3} (x + 6) = 3( - 8)[/tex]

2(x+6) = -24

______________________________________

STEP 2:

Divide both sides by 2:

[tex] \frac{2(x + 6)}{2} = \frac{ - 24}{2} [/tex]

________________________________

STEP 3:

Simplify:

[tex]x + 6 = - 12[/tex]

Subtract 6 from both sides:

[tex]x + 6 - 6 = - 12 - 6[/tex]

________________________________

STEP 4:

[tex]x = - 18[/tex]

Therefore, your answer is -18.

Solve the inequality for x.
- 4x + 16 > -64
A)
X> 12
B)
X > 20
x < 12
D
x < 20

Answers

Answer:

D: x < 20

Step-by-step explanation:

-4x + 16 > -64

subtract 16 from both sides because you must isolate x.

-4x + 16 - 16 > -64 - 16

-4x > -80

Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...

-4x/ -4 < -80/ -4

        x < 20

(negative divided by a negative will result in a POSITIVE.)

The area of a trapezoid is 15 cm2. The height is 3 cm, and the bases have lengths of 2x and 3x cm. Find x, and give the lengths of the two bases.

Answers

Answer:

x = 2, bases are 4 cm and 6 cm

Step-by-step explanation:

Area formula:

A = 1/2(b1 + b2)h

Substitute the given values:

15 = 1/2(2x + 3x)(3)1/2(15x) = 15x = 2

The bases are:

b1 = 2*2 = 4 cmb2 = 3*2 = 6 cm

Solve using the order of operations. (9+9+72)-4+9

PLZ ANSWER PLZ HURRY​

Answers

Answer:

95

Step-by-step explanation:

The order of operations is PEMDAS

Equations in PARENTHESES come first

Numbers with EXPONENTS come second

MULTIPLICATION/DIVISION problems come next (depending on which comes first in the equation

ADDITION/SUBTRACTION comes last (again, depending on which comes first in the equation)

So we do (9+9+72) first

So that equals 90

And then we subtract 4 from 90

90 - 4 = 86

Then we add 9 to 86

86 + 9 = 95

Answer: 72 is the answer
