It's true, just draw the sides and you'll see there's no other angle you could get.
Answer:
a= -12 and b=36
Step-by-step explanation:
a+b=24 and 3a+b
a-3a+b=24
-2a+b-b=24
-2a/-2=24/-2
a= -12
then substitute the value of a in a+b=24 to get the value of b
so let see -12+b=24
b=24+12
b=36
we can check it by the equation -2a+b-b=24
-2(-12)+36-36=24
24=24 so as you have seen the answer is correct
thanks!!!
First either add or subtract the number in the parenthesis (3^2-4) which equals to 5
90/[10+5) add the number in the parenthesis again (always do the parenthesis first) [10+5]= 15.
lastly divide 90/15 which equals to 6
always remember (PEMDAS)
Answer:
see explanation
Step-by-step explanation:
To factorise the quadratic consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x term.
product = 2 × - 6 = - 12 and sum = + 11
The factors are + 12 and - 1
Use these factors to split the middle term
2x² + 12x - x - 6 = 0 ( factor the first/second and third/fourth terms )
2x(x + 6) - 1(x + 6) = 0 (factor out (x + 6) )
(x + 6)(2x - 1) = 0
equate each factor to zero and solve for x
x + 6 = 0 ⇒ x = - 6
2x - 1 = 0 ⇒ x =
