Factorise fully x^2-3x+2
mr Goodwill [35]

Answer:

(x−1)(x−2)

Step-by-step explanation:

The middle number is -3 and the last number is 2.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -3

Multiply together to get 2

Can you think of the two numbers?

Try -1 and -2:

-1+-2 = -3

-1*-2 = 2

Fill in the blanks in

(x+_)(x+_)

with -1 and -2 to get...

The label on a 1 1/2pound bag of wildflowers seeds states that it will cover an area of 375 square feet. Based on this informati
BaLLatris [955]

Answer:

250 square feet

Step-by-step explanation:

This problem can be easily solved using ratios.

It says that  1\frac{1}{2} pound covers 375 sq. ft.

So, how much would 1 pound cover?

Let 1 pound cover "x" pounds. We can setup up two ratios and equate them. Then cross multiply and solve for x.

Note:  Pounds on numerator and Square Feet on denominator

\frac{1\frac{1}{2}}{375}=\frac{1}{x}\\1\frac{1}{2}*x=375*1\\1\frac{1}{2}x=375\\\frac{3}{2}x=375\\x=\frac{375}{\frac{3}{2}}\\x=375*\frac{2}{3}\\x=250

Hence, 1 pound of wildflower seeds will cover an area of 250 square feet

Eighth grade > W.14 Solve equations: word problems HCP
Firdavs [7]

Answer:

Andrew has been in the book club for 18 months.

Step-by-step explanation:

The number of books already read by Andrew = 13 books

He reads 1 book each month after joining the book club.

Number of books he has read after joining the club = 31 books

Number of books read after joining the Club

=  Total books Read  - Books read beforehand

=  31 books   -  13 books

= 18 books

So, the number of books Andrew read within the club = 18 books

Now, as Andrew read 1 book per month

⇒ Andrew reads 18 books in   18 x ( 1 Month)  = 18 Months

Hence,  Andrew has been in the book club for 18 months.
