Answer:
You simply substitute 8 for n
A₈ =3(8)+4=28
Answer:
The value of x is 23.
Step-by-step explanation:
Consider the below figure attached with this question.
Form the given figure it is clear that 
The sum of all exterior angles of a quadrilateral is 360°.

On combining like terms we get



Divide both sides by 15.

Therefore, the value of x is 23.
Answer: 9p - 1.5a
Step-by-step explanation:
Your maximum heart rate is about 220 minus your age. But it varies base on age category.
Target heart rate during moderate intensity activities is about 50-70% of maximum heart rate.
According to the question;
Target heart rate for
women = 1/2p(418-4a)
= 209p - 2a ....... (1)
men = 1/2p(400-a)
= 200p - 0.5a .......(2)
To find the difference between the target heart rates for a fit woman and a fit man, take equation 1 from equation 2
(209p - 2a) - (200p - 0.5a)
209p - 2a - 200p + 0.5a
9p -1.5a
Answer:
43° is correct answer
Step-by-step explanation:
Like me
Expanded form is when you just write it out.
so 9 cubed becomes:
9×9×9
and 20 squared becomes:
20×20
the exponent tells you how many times to multiply that number by itself. so, whenever it asks for expanded form, you just write the number how ever many times the exponent tells you to and multiply them all.
