Answer:

Step-by-step explanation:

question 1. 13) 1/2 ( 4a + 12) =

(13(1/2) ) (4a) + (13(1/2) ) (12) = 26a+78

question 2. (14)(4)b2+3.5−2a+3.5b2−a

=56b2+3.5+−2a+3.5b2+−a

Combine Like Terms:

=56b2+3.5+−2a+3.5b2+−a

=(56b2+3.5b2)+(−2a+−a)+(3.5)

=59.5b2+−3a+3.5

Step-by-step explanation:

Formula:

$\boxed{a = 3.14(r)^{2} }$

r represents the radius.

The radius is 1/2 of the diameter.

Since 1/2 of 16 is 8, 8 is our radius.

Substitute:

$a = 3.14(8)^{2}$

Solve:

$a = 3.14(64)$

$a = 200.96in^{2}$

Help a girl out with geometry

Darya [45]

Follow the steps

106=x+79+x+45
106=2x+124
-124= -124
-18=2x
( -18)/2=(2x)/2 <----- solving for x
-9=x

then
angle LMF= -9+79
=70

angle FMN= -9+45
= 36
(when you add 70 and 36 together you get 106 which is the measurement of angle LMN or in other word the whole thing)

In conclusion the answer to the problem is:
Angle LMF is equal to 70.

Answer:

first answer is correct

Step-by-step explanation:

Hello, we want to write 2 + 4 + 6 + ... + 20

for n = 1, 2n = 2*1 =2

for n = 2, 2n = 2*2=4

for n = 3, 2n=2*3=6

etc

$\displaystyle \sum_{n=1}^{10} {2n} = 2*1 + 2*2 +2*3+2*4+...+2*10=2+4+6+8+...+20$

thanks
