Factor the following trinomial completely 3x^2+15x+18

1 answer:

3 0

This is an easy problem

The first ring to do is divide all of the terms by 3

You get x^2+5x+6

Then you factor it normally
(x+2)(x+3)

Knut had picked strawberries during the summer holidays. First days he picked 9090 baskets of strawberries! The next day he was

jasenka [17]

Answer:

190 baskets of strawberries

Step-by-step explanation:

The question is incomplete as it didn't state what we are to determine from the information given.

Let's determine total amount picked in the three days.

1st day picked 90strawberries

Amount of strawberries on 2nd day = 2/3 of the amount picked 1st day

= (2/3)(90)

Amount of strawberries on 2nd day = 60 baskets of strawberries

Amount of strawberries picked on 3rd day = (2/3) of the amount picked 2nd day

= (2/3) (60)

Amount of strawberries picked on 3rd day = 40 basket of strawberries

Total amount picked for 3 days = 90+60+40

= 190 baskets of strawberries

Identify an equation in point-slope form for the ine parallel to y = -2/3 x+8 that

zlopas [31]

Answer:

$y +5 = -\frac{2}{3}(x - 4)$

Step-by-step explanation:

Given

$y = -\frac{2}{3}x + 8$

Point (4,-5)

Required

Determine the line equation

From the question, we understand that the line is parallel to $y = -\frac{2}{3}x + 8$

This implies that they have the same slope, m

A linear equation is:

$y = mx + b$

Where

$m = slope$

By comparison: $y = mx + b$ and $y = -\frac{2}{3}x + 8$

$m = -\frac{2}{3}$

Next, we determine the line equation using:

$y - y_1 = m(x - x_1)$

Where

$(x_1,y_1) = (4,-5)$ and $m = -\frac{2}{3}$

$y - (-5) = -\frac{2}{3}(x - 4)$

$y +5 = -\frac{2}{3}(x - 4)$

Hence,

<em>Option C is correct</em>

The sum of two numbers is 62, and their difference is 8. What are the<br> numbers?

Marina CMI [18]

Answer: 35 and 27

Step-by-step explanation:

We can solve this by using a system of equations

x will be the first number while y will be the second

$x+y=62$

This equation means the two numbers will add to get 62

$x-y=8$

This equation means when subtracted the two numbers will have the difference of 8.

Now I will solve by elimination

$x+y=62\\\\+x-y=8\\2x=70$

When adding the two equations why was eliminated so now we can find the value of x

$2x=70\\\frac{2x}{2} =\frac{70}{2} \\x=35$

Now sub in x into one of the original equations to find the value of y

$35+y=62\\35-35+y=62-35\\y=27$
