Answer:

18 6/7

Step-by-step explanation:

The circumference = $diameter * \pi$

In this problem, the diameter is 6 cm and $\pi = 22/7$

6 * 22/7 = 18 6/7

So, the circumference is 18 6/7

Hope this helps :)

The measures of the angles of a triangle are shown in the figure below. Solve for x.

Sindrei [870]

Answer:

x=5

Step-by-step explanation:

We know that the angels in a triangle are equal to 180.

(6x+20)+(7x-10)+105=180

We open the prentices and simplify.

13x+115=180

Now we can subtract 115 on both sides.

13x=65

At last, we can divide by 13 on both sides to get the result of x.

x=5

A right triangle's height is 3 times the length of its base. if the area of the triangle is 486, what is the height?

Irina-Kira [14]

The formula of the area of a triangle:
$A_\Delta=\dfrac{bh}{2}$
b - the bash - the height
We have:
b - the base3b - the height486 - the area

Substitute:
$\dfrac{3b\cdot b}{2}=486\ \ \ |\cdot2\\\\3b^2=972\ \ \ |:3\\\\b^2=324\to b=\sqrt{324}\\\\b=16\to h=3b=3\cdot18=54$
Answer: The length of the height is equal 54 units.

Asking again... Please help! 1/20, will give brainliest. I do not tolerate spam answers!

Answer:

(x + 7)(x + 5)

Step-by-step explanation:

Given

x² + 12x + 35

Consider the factors of the constant term (+ 35) which sum to give the coefficient of the x- term (+ 12)

The factors are + 7 and + 5 , since

7 × 5 = + 35 and sum = 7 + 5 = + 12, then

x² + 12x + 35 = (x + 7)(x + 5) ← in factored form
