8x = 80 ---divide both sides by 8 ---division property
x = 80/8
x = 10
Answer:
(3x+1)(5x-2)
Step-by-step explanation:
Given the expression
15x^2-6x+5x-2
Factorize;
3x(5x-2)+ 1(5x-2)
(3x+1)(5x-2)
Hence the factorized form is (3x+1)(5x-2)
Sometimes it will, and sometimes it won't.
I reason as follows:
(21 + x) + (30 + 2x) = 51 + 3x has an 'x' term
(42 + x) + (30 - x) = 72 has no 'x' term.
Answer: 740000000
Step-by-step explanation:
Given that, one side of the garden be 10 feet long.
So, length : l = 10 feet.
And the other side will be 5 less than three times the first side.
So, width = 3l - 5
= 3(10) - 5 Since l: length = 10
= 30 - 5
= 25
So, area = Length * width
= 10 * 25
= 250.
So, the area of Mark's garden is 250 square feet.
Hope this helps you!
