(x+6)(x+2)=60
expand
x^2+6x+2x+12=60
x^2+8x+12=60
minus 60 both sides
x^2+8x-48=0
factor
what multiplies to -48 and adds to 8
-4 and 12
(x-4)(x+12)=0
set each to zero

x-4=0
x=4

x+12=0
x=-12

x=4 or -12

solutions are x=-12 and 4

Answer:

\sqrt{655*655} =655

Step-by-step explanation:

655*655 is pretty much equal to 655²

the square root of a number to the power of 2 is equal to the number without the power

so √655² would be equal to 655

The value of angle x is 53° for the given triangle.

<h3>What is angle?</h3>

An angle is the formed when two straight lines meet at one point, it is denoted by θ.

In the given isosceles triangle,

one angle is 74°,

Since, two sides of the isosceles triangle are equal, so the corresponding angles will be equal to x.

The sum of angles of a triangle = 180°

x + x + 74 = 180

2x = 106

x = 53

The required value of angle x is 53°.

Which expression is equivalent to
deff fn [24]

Answer:

b) log8 4 + log8 a + log8 (b- 4) - 4 log8 c

Step-by-step explanation:

The given expression is log8 4a ((b - 4) ÷ c^4)

Here we have to use the quotient rule.

log(a/b) = log a - log b

log8 4a (b- 4) - log8 4a(c^4)

Using the product rule log(ab) = log (a) + log (b)

log8 4a + log8 4a(b-4) - log8 4a - log8 (c^4)

log8 4a(b - 4) - log8 (c^4)

log8 4a + log8 (b- 4) - 4 log8 c

Again using the product rule.

log8 4 + log8 a + log8 (b- 4) - 4 log8 c

So it is b.

Thank you.
