Answer:

(x+7)(x-2)

Step-by-step explanation:

=x^2+5x-14

=x^2+(7-2)x-14

=x^2+7x-2x-14

=x(x+7)-2(x+7)

=(x+7)(x-2)

Answer:  (x+7)(x-2)

We're looking for two numbers that multiply to -14 and also add to 5. Through trial and error, you should find those numbers are 7 and -2.

You can use the FOIL rule to confirm that (x+7)(x-2) expands out to x^2+5x-14

(x+7)(x-2) = x^2-2x+7x-14 = x^2+5x-14

Answer:

3 x 10^8

Step-by-step explanation:

300,000,000 in scientific notation is 3 x 10^8 and because it’s 8 zeros

The number 300,000,000 represented in scientific notation will be 3 × 10⁸. Then the correct option is A.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

According to the U.S. Geological Survey, there are over 300,000,000 cubic miles of water on the planet.

Convert the integer number into scientific notation. Then the number can be written as,

300,000,000 = 3 × 10⁸

The number 300,000,000 represented in scientific notation will be 3 × 10⁸. Then the correct option is A.

Answer:

There are 15.748 inches in 40cm. Can I please have brainlest?

Step-by-step explanation:

Answer:

40cm

Step-by-step explanation:

If you are converting 40cm to one inch and the conversion ratio is 2.54 : 1, you would place 40 in the numerator as the original ration has 2.54/1 as a fraction and the same will apply to 40cm.

** This applies if you are finding which number is in the numerator and not the answer to how much 40cm in inches is.

Answer:

n = 5.75

Step-by-step explanation:

Step-by-step explanation:

(1, −1), (−2, −7), (0, 1), (−1, −1) and (−5, 2), (2, 6), (3, 2), (4, −5) are functions because each x value corresponds to exactly one y value. a function must have only one output value for each input value.

Bc yes

Answer:

[tex] c = \dfrac{3e + 3d - 5D}{2b} [/tex]

Step-by-step explanation:

[tex] \dfrac{2bc + 5D}{3} = e + d [/tex]

Multiply both sides by 3.

[tex] 2bc + 5D = 3(e + d) [/tex]

[tex] 2bc + 5D = 3e + 3d [/tex]

Subtract 5D from both sides.

[tex] 2bc = 3e + 3d - 5D [/tex]

Divide both sides by 2b.

[tex] c = \dfrac{3e + 3d - 5D}{2b} [/tex]

Answer:

x=-35/6

Step-by-step explanation:

2 + 3( 4x + 5) = -53

subtract 2 from both sides= 3(4x+5)=-55

divide both sides by 3 = 4x+5=-55/3

subtract both sides by 5 = 4x=-70/3

divide both sides by 4 = x=-35/6

x=-35/6 is your final answer

Answer:

Hope this helps :)

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Exact Form:

x=−35/6

Decimal Form:

x=−5.8¯3 (Repeating)

Mixed Number Form:

Answer:

D

Step-by-step explanation:

The hypotenuse squared is equal to the sum of the legs squared in a right triangle.

∴ c² = a² + b² (Pythagorean’s Theorem)

c² = 3.4² + 6.7² (substitute the given values for a & b)

c² = 11.56 + 44.89 (square both right hand terms)

c² = 56.45 (add the right hand side values)

c = √56.45 (square root of both sides)

c ≈ 7.5 to the nearest tenth QED
