Express 26 divide 4 +root3 in form a +b root3 where a and b are integres​

8 - 4

Step-by-step explanation:

Given:

To express the given question in the form a + b, we first have to rationalize the denominator of the expression.

Rationalizing the denominator, we have;

*  =

=

 =

= 2(4 - )

= 8 - 4

The required form of the given question is therefore 8 - 4

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
