Answer:

Step-by-step explanation:

Use FOIL method

1) (x +4 )(3x +2) = x*3x + x*2 + 4*3x + 4*2

                        = 3x² + 2x + 12x + 8

                        = 3x² + 14x + 8

4) (4x - 1) (2x + 7) = 4x*2x + 4x*7 + (-1)*2x + (-1) * 7

                           = 8x² + 28x - 2x - 7

                            = 8x² + 26x - 7

What is the 9th term of the geometric sequence 4, −20, 100, …?
sveta [45]
First, we are going to find the common ratio of our geometric sequence using the formula: r= \frac{a_{n}}{a_{n-1}}. For our sequence, we can infer that a_{n}=-20 and a_{n-1}=4. So lets replace those values in our formula:
r= \frac{-20}{4}
r=-5

Now that we have the common ratio, lets find the  explicit formula of our sequence. To do that we are going to use the formula: a_{n}=a_{1}*r^{n-1}. We know that a_{1}=4; we also know for our previous calculation that r=-5. So lets replace those values in our formula:
a_{n}=4*(-5)^{n-1}

Finally, to find the 9th therm in our sequence, we just need to replace n with 9 in our explicit formula:
a_{9}=4*(-5)^{9-1}
a_{9}=4*(-5)^{8}
a_{9}=1562500

We can conclude that the 9th term in our geometric sequence is <span>1,562,500</span>

Sophia scored 92% in a math test. if the test had 50 question how many did she get right
german

Answer: 46

Step-by-step explanation:

percentage scored = 92

number of correct question = x

total number of questions = 50

The formula for calculating the percentage scored

= number of correct question / total number of questions x 100

That is

92 = \frac{x}{50} x \frac{100}{1}

92 = \frac{100x}{50}

cross multiplying :

100x = 92 x 50

100x = 4600

dividing through by 100 , we have

x = 46

Therefore, she got 46 questions right
