Answer:

x > 6

Step-by-step explanation:

3x + 7 > x + 19

Subtract x and 7 on both parts.

3x - x > 19 - 7

Subtract like terms.

2x > 12

Divide 2 into both parts.

x > 12/2

x > 6

The diameter of a circle is 8 cm. Find its area in terms of π.

Verizon [17]

Answer:

$16\pi$ $cm^2$

Step-by-step explanation:

Area of a circle is equal to $\pi r^2$ , where r is the radius

$A=\pi r^2$

A diameter is twice the length of the radius. ( $8/2$ )

So the radius is 4 cm.

$r^2=4^2=16$

so the Area is $16\pi$

Brums [2.3K]

Sorry to disappoint, but none of these answers are correct. All three limits are equal to 7.

Compute the one-sided limits:

$\displaystyle\lim_{x\to2^-}h(x)=\lim_{x\to2}(x^2-x+5)=2^2-2+5=7$

$\displaystyle\lim_{x\to2^+}h(x)=\lim_{x\to2}(x^3-1)=2^3-1=7$

Both the one-sided limits agree, so the two-sided limit has the same value,

$\displaystyle\lim_{x\to2}h(x)=7$
