Which expression can be added to the right side of the equal sign to form an equation? 30+2* 1. 3(2+3) 2. 7(2+1) 3. 6(3+7) 4. 5(4+1)

we will use

this rule in order of operation

P: Parenthesis

E: Exponent

M: Multiplication

D: Division

A: Addition

S: Subtraction

we are given

30+2*10....

we can simplify it

now, we will check option and verify whether it is equal to 50

option-a:

3(2+3)

=3*5

=15

so, this is FALSE

option-b:

7(2+1)

=7*3

=21

so, this is FALSE

option-c:

6(3+7)

=6*10

=60

so, this is FALSE

option-d:

5(4+1)

=5*5

=25

so, this is FALSE

55/i dont know i do it for the points

step-by-step explanation:

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
