URGENT!!Find The Area And Perimeter Of Each Figure Below.

Answers

Answer 1

Answer:

Perimeter= 221, Area=

Step-by-step explanation:

Perimeter is always addition of all sides.

73+56+92=221

Area=

S= (a+b+c)/2

= (73+92+56)/2

=221/2

ar(triangle)= [tex]\sqrt{221(221-92)+221(221-73)+221(221-56)}[/tex]

You invested ​$20,000 in two accounts paying 7% and 8% annual​ interest, respectively. If the total interest earned for the year was $1530, how much was invested at each​ rate?

Answers

Answer:

$7,000 at 7%; $13,000 at 8%

4x 2 = 36

Answers

Answer:

the answer will be 4x²...last option

Answer:

Answer is 4x² = 36

Step-by-step explanation:

Let that number be x:

[tex]4 \times x {}^{2} = 36 \\ {4x}^{2} = 36[/tex]

further more:

[tex] {x}^{2} = \frac{36}{4} [/tex]

take a square root:

[tex] \sqrt{ {x}^{2} } = \sqrt{ \frac{36}{4} } \\ \\ x = \frac{ \sqrt{36} }{ \sqrt{4} } \\ \\ x = \frac{6}{2} \\ \\ x = 3[/tex]

write an explicit and recursive formula for the sequence -4, -6, -8, 10

Answers

Answer:

Each term is 2 greater than the term before it. Thus for any given term, an, our equation is:

an=2n

We can write this in a form closer to standard, by noting that a1=2, so we can make it dependent on a1..

an=a1+2(n−1)=2+2(n−1)

Answers

Answer:

Step-by-step explanation:

The equation has to be

8x + 20 = 148                  Subtract 20 from both sides

8x = 148 - 20                  Combine

8x = 128                          Divide by 8

x = 128/8                        

x = 16

Answer : 16
Step by step explanation :

Step 1 : subtract 20 from the 148.
148 - 20 = 128
Step 2 : divide 128 by 8.
128/8 = 16

Therefore the answer is 16, please mark brainliest if possible. Have a nice day!
