Answer:

12x² - 13x - 14

Step-by-step explanation:

 (3x+2)(4x-7)

Multiply  3x by 4x - 7 and +2 by 4x - 7. That is

3x ( 4x -7) + 2 ( 4x - 7)

(3x × 4x)  - (3x × 7 ) + (2× 4x) - (2×7)

= 12x²  - 21x + 8x - 14

Note : -21x + 8x = -13x.

Therefore

= 12x² - 13x - 14

Answer:

You "FOIL" (First, Outer, Inner, Last).

12x^{2}  - 13x - 14

Step-by-step explanation:

You "FOIL" (First, Outer, Inner, Last). Basically, you have to multiple each term by each of the other terms.

(3x+2)(4x-7)

(3x)(4x) + (17)(3x) + (2)(4x) + (2)(-7)

12x^2 - 21x + 8x - 14

12x^2 - 13x - 14

Answer:

The approximated length of EF is 2.2 units ⇒ A

Step-by-step explanation:

<em>The tangent ratio in the right triangle is the ratio between the opposite side to the adjacent side of one of the acute angle in the triangle</em>

In the given figure

∵ The triangle DFE has a right angle F

∵ The opposite side to angle D is EF

∵ The adjacent side to angle D is DF

→ By using the tangent ratio above

∴ tan(∠D) = \frac{EF}{DF}

∵ DF = 6 units

∵ m∠D = 20°

→ Substitute then in the ratio above

∴ tan(20°) = \frac{EF}{6}

→ Multiply both sides by 6

∴ 6 tan(20°) = EF

∴ 2.183821406 = EF

→ Approximate it to the nearest tenth

∴ 2.2 = EF

∴ The approximated length of EF is 2.2 units

24. Find the area of the shaded region:
Monica [59]

Answer:

A = 5x³ + 17x² - 35x - 30

Step-by-step explanation:

the shaded area (A) is calculated as

A = outer area - inner area

   = (5x + 3)(x² + 4x - 10) - 3x(2x - 1) ← distribute parenthesis

   = 5x³ + 20x² - 50x + 3x² + 12x - 30 - (6x² - 3x)

  = 5x³ + 23x² - 38x - 30 - 6x² + 3x ← collect like terms

  = 5x³ + 17x² - 35x - 30

Explain how to estimate the quotient using compatible<br>numbers.plz help fast ​
Nadya [2.5K]

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

To estimate the quotient, make the fractions "like" fractions. To do this, you need to make the fractions have the same denominator, and turn them into improper fractions.

Step-by-step explanation:

27\frac{2}{3} = 27 \frac{20}{30}

3\frac{9}{10} = 3\frac{27}{30}

Now the denominators are the same --> they are "like" fractions.

27\frac{20}{30} + 3\frac{27}{30} = ?

27\frac{20}{30} + 3\frac{27}{30} = (27 + 3) + (\frac{20}{30} + \frac{27}{30})

27\frac{20}{30} + 3\frac{27}{30} = (30) + (\frac{47}{30})

27\frac{20}{30} + 3\frac{27}{30} = (30) + (1 \frac{17}{30})

27\frac{20}{30} + 3\frac{27}{30} = 31 \frac{17}{30}

Your answer is 31\frac{17}{30}.

I hope this helps!
