If youre just asking for this to be solved the answer is 17, you would do parenthesis first which is 3+1=4, then 12/4= 3, then 6+3=9, 2 X 9= 18, 18-1= 17

How many solutions does this equation have?

kozerog [31]

Hello from MrBillDoesMath!

Answer: infinite solutions

Discussion: I did a double take on this one but the left hand is

a + 3 + 2a = 3a +3

and the right hand side is

-1 + 3a + 4 = 3a + (4-1) = 3a + 3

The left and right sides of the equation are identical for all "a", i.e. for infinitely many "a" values.

Regards, MrB.

What is the base of a triangle with a height of 14 cm and an area of 42 square cm?

sasho [114]

Answer:

$6cm$

Step-by-step explanation:

$area = \frac{1}{2} \times base \times height \\ 42 = \frac{1}{2} \times b \times 14 \\ 42 = \frac{14b}{2} \\ 42 = 7b \\ \frac{42}{7} = \frac{7b}{7} \\ base = 6cm$
