Rina8888 [55]

Step-by-step explanation:

first number=x

second number=x+2

third number=x+4

(x+2)(x+4)=35

x(x+4)+2(x+4)=35

x²+4x+2x+8=35

x²+6x+8=35

x²+6x=35-8

x²+6x=33

x²+6x-33=0

using that, you can find the first number,

then use the data to find the other two.

Lindsay invested $4500 at 4% interest compounded annually.
goldfiish [28.3K]

Answer:

\$2,161.1

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=10\ years\\P=\$4,500\\ r=0.04\\n=1  

substitute in the formula above  

A=\$4,500(1+\frac{0.04}{1})^{1*10}  

A=\$4,500(1.04)^{10}

A=\$6,661.10    

Find the interest

I=A-P

I=\$6,661.10-\$4,500=\$2,161.1

Answer this for me plz.?
Elis [28]

Step-by-step explanation:

Length = x-3

width = x+8

Area of the rectangle = 60 inch²

(x-3)(x+8)=60

x²+8x-3x-24=60

x²+5x-24=60

x²+5x-84=0

x²+12x-7x-84=0

x(x+12) - 7(x+ 12) =0

(x+12)(x-7)= 0

x= -12 or, x= 7

Measure of sides of rectangle can never be negative.

Answers:

Therefore,

x=7

Dimensions

length =7-3

=4 inches

width = 7+8

=15 inches
