You did a good job of sharing this quadratic equation in proper symbolic notation, but you haven't yet shared the instructions for this problem.

I will assume that you are to find the roots / zeros of a^2+5a+6=0. Factoring results in (a+3)(a+2)= 0, from which we deduce that a = -3 and a = -2.

The solution set is {-3, -2}.

we are given

a^2+5a+6=0

we can use factoring formula

a^2-(m+n)a+mn=(a-m)(a-n)

we can compare

and we get

m+n=-5

mn=6

now, we can solve for m and n

and we get

m=-3 , n=-2

now, we can use formula

and we get

a^2+5a+6=(a+3)(a+2)

now, we can set it equal to 0

a^2+5a+6=(a+3)(a+2)=0

(a+3)=0

a=-3

a+2=0

a=-2

so, we will get

a=-2,a=-3.............Answer

Lelu [443]

Answer:

x and y are 5.66 units

Step-by-step explanation:

The triangle above is a right angled triangle ; and can be solved using trigonometric relation :

Using :

Sin 45 = opposite / hypotenus

Opposite = y ; hypotenus = 8

Sin 45 = y/8

y = sin 45 * 8

y = 5.66 units

Side length x ;

Sin 45 = opposite / hypotenus

Sin 45 = x / 8

x = sin 45 * 8

x = 5.66 units

slamgirl [31]

Answer:

16 = small

74 = big

Step-by-step explanation:

4x+10 = big angle

x = small angle

4x+10+x = 90

5x+10 = 90

5x = 80

x = 16

4 x 16 + 10 = 74
