If ∠A and ∠B are complementary, find the value of x given that ∠A=3x-2 and ∠B=x+12

xxMikexx [17]

Answer:

x=20 degrees

Step-by-step explanation:

complementary means the angles equal 90 degrees

so ∠A+∠B=90 degrees

∠A=3x-2 and ∠B=x+12

so subsitute

(3x-2)+(x+12)=90

then solve for x

4x+10=90

4x=80

x=20 degrees is your answer

What is the factorization of the polynomial below?<br> 5x2 - 35x + 60

natita [175]

Answer:

$5(x-3)(x-4)$

Step-by-step explanation:

$5x^2-35x+60$

Start by factoring out a 5:

$5(x^2-7x+12)$

We need to find two integers that have a product of 12, and a sum of -7:

(-3)(-4)=12

-3-4=-7

We can split -7x into -3x and -4x

$5(x^2-3x-4x+12)$

Factor each half separately:

$5[x(x-3)-4(x-3)]$

Since x and -4 are both being multiplied by x-3, we can combine them:

$5(x-3)(x-4)$
