This is the concept of algebra, to factor the expression we proceed as follows;
ab+4+a+4b
this can be written as:
ab+a+4+4b
factoring this we get:
a(b+1)+4(1+b)
=(a+4)(b+1)
the answer is (a+4)(b+1)
It would take tina 4.2
what i did was i multiplied 7x6=42
then i divided 42 with 10
42/10=4.2
so it’ll take tina 4.2 miles
Hi there. I'm going to answer using the methods I currently know - which means I'll answer it in two parts.
So, I'm going to use the Pythagorean theorem and the formula for the area of a triangle.
42.1² - 34.3² = 595.92

= 24.41
Area of a triangle =


= 418.63
