7x + 7 = 112

-7

7x = 105

divide 7

x = 15

Now, for y.

Angle 112 and the unknown angle = 180*

This means the unknown angle = 68

4y = 68

divide 4

y = 17

4y+112=180 angle sum property
Therefore,
4y=180-112
= 68
As 4y=68 then y = 17

Now,
4y +7x+7=180 angle sum property
7x =180-68-7
7x=105
X=15

Solve the eqauation 76a^3+19a^2+16a=-4
Crazy boy [7]

Answer:

The solutions are a₁ = -4/19 i, a₂ = 4/19 i and a₃ = -1/4

Step-by-step explanation:

Given the equation 76a³+19a²+16a=-4, for us to solve the equation, we need to find all the factors of the polynomial function. Since the highest degree of the polynomial is 3, the polynomial will have 3 roots.

The equation can also be written as (76a³+19a²)+(16a+4) = 0

On factorizing out the common terms from each parenthesis, we will have;

19a²(4a+1)+4(4a+1) = 0

(19a²+4)(4a+1) = 0

19a²+4 = 0 and 4a+1 = 0

From the first equation;

19a²+4 = 0

19a² = -4

a² = -4/19

a = ±√-4/19

a₁ = -4/19 i, a₂ = 4/19 i (√-1 = i)

From the second equation 4a+1 = 0

4a = -1

a₃ = -1/4
