Step 1:
x² + 4x = 192
Step 2:
Take x common:
x ( x + 4) = 192
Length is x and width is x+4
Step 3:
x² + 4x - 192 = 0
Step 4:
x² + 16x - 12x - 192 = 0
x(x+16) - 12(x+16) = 0
(x-12)(x+16) = 0
⇒ x=12, x=-16
Because the length can't be -16, the length is 12.
6pens cost=20p×6=120p
5pencils cost=12p×5=60p
total =6pens+5pencils
=120p+60p
=180p
⇒1rupee 80p
The y-intercept of the graph is 0
Answer:
-5, -1, 0, |-1|, |-3|
Step-by-step explanation:
|-3| = 3
|-1| = 1
-5, -1, 0, 1, 3
Note that abosulate value changes the number to being positive at all times.
Best of Luck!
The two numbers are 19 and 6, and their product is 114.
