1. Two consecutive integers means that the values are whole numbers and they are located right after the other (eg. 2, 3).

Now, let us call the smaller value x. The consecutive value will be one greater than x, thus the larger value may be written as x + 1.

2. We know that the product of the two values is 420. Given that the smaller value is x and the larger value is x + 1, we can write this as:

x(x + 1) = 420

3. Now we can expand to get:

x^(2) + x = 420

4. Now subtract 420 from both sides to get:

x^(2) + x - 420 = 0

Therefor, the constant of the quadratic expression is -420.

Janet is buying a $28 necklace. The store reduces the price by 20% and then applies a $2 off coupon. How much will Janet pay for
Leokris [45]
Okay well the starting is 28 dollars, right. But since there is a 20 percent discount, you have to turn 20% to a decimal. That means moving the decimal sign twice to the left to make it .20. From the it would be .20*28, that should equal 5.6. Now, that 5.6 is the amount you have to take away, it is the price of the sale. From then, you subtract which is 28-5.6 which should be 22.4. From that 22.4 you now take away two dollars and then it should be 22.4-2 which should be 20.4. Now that is your answer, 20.4.

Given the measures a = 10, b = 40, and A = 30°, how many triangles can possibly be formed?
arlik [135]

Answer:

no triangle can be formed with the given values (i.e 0 triangle).

Step-by-step explanation:

Given;

length of side a, = 10

length of side b, = 40

angle A, = 30°

Apply sine rule to determine the angle of the second side (B);

\frac{sin \ A}{a} = \frac{sin \ B}{b} \\\\\frac{sin \ 30^0}{10} = \frac{sin \ B}{40}\\\\sin \ B = 40(\frac{0.5}{10} )\\\\sin \ B = 2

The maximum sine function is 1, there is no sine function that will be equal to 2, so there is no triangle that can be formed with the given values.

Elis [28]

I can help! With the Greatest Common Factor you figure out the greatest number that can go into all numbers. The number here would be the 2. You then divide 2 by all the numbers in the problem.
You would end up getting x^2 + 6x + 9


I use to struggle with this too. Hope this helps! Have a great day!!

kondor19780726 [428]

Answer:

Alonzo was billed for 111 minutes.

Step-by-step explanation:

In this situation, lets let x = minutes.

0.08x+6=14.88

Subtract the 6 from both sides of the equation.

0.08=8.88

x=8.88÷0.08=111
