babymother [125]

Answer:

20 percent decrease

Step-by-step explanation:

0.15 cents is 10 percent of 1.50, and that multiplied by 2 is 0.30 cents. 0.30 cents is equal to 20 percent, and the difference between 1.50 and 1.20 is 30 cents.

Need help with 35 thank you so much!!

Yakvenalex [24]

If a pentagon is regular, then all of the sides are the same length. This means that

$5x-4=2x+11 \iff 5x-2x = 11+4 \iff 3x=15 \iff x = 5$

So, if $x=5$ , the lengths of the sides evaluate to

$5x-4 = 25-4=21,\quad 2x+11=10+11=21$

So, all the sides of the pentagon are 21 units long, and AB is 21 units long as well, because all sides are the same length.

Hi..... the domain(D) will be:

$\mathtt {f(x)=\dfrac{13}{3-x}\rightarrow \boxed{D=\{x\in R\,|\,x\neq 3\}}}$

Thanks... :)
