Answer:
If your quadratic equation it is in the form of x^2+bx+c=0 (in other words, if the coefficient of the x^2 term=1), it's possible (but not guaranteed) that a relatively simple shortcut can be used to factor an equation. Find two numbers that both multiply to make C and add to make B.
Step-by-step explanation:
Let the cost of soap be x,
cost of razors = x + 2.5
total cost = 2x + 2.5
2x + 2.5 = 5.5
2x = 3
x = 1.5
cost of razors = 1.5 + 2.5
= 4
The cost of the packet of razors and bar of soap is £4.00 and £1.50 respectively.
Answer: option c is the correct answer
Step-by-step explanation:
The rectangular garden has equal lengths and equal widths.
The area of the rectangular garden is expressed as length of the rectangular field × width of the rectangular field.
From the information given, the length if the rectangular field is 2x+4 while the width of the rectangular field is 4x−6. The area of the rectangular field becomes
Area = (2x + 4)(4x - 6)
Area = 8x^2 - 12x + 16x - 24
= 8x^2 + 4x - 24
Answer:
7
Step-by-step explanation:
make a number line from 0 to -12. Find -5 as well as, -12. then count how many times it takes you to get from -5 to -12.
OR
you can just do 12-5=7
Hope this helped
