Please help me with math

A=17cm , B=3cm , C=26cm , D=8 miles , E-5cm

Step-by-step explanation:

A-

Length a= 10 Length, b= 14 and Length c= ?

Use the equation + =

Apply the equation-

+ = 296 (keep in mind this is squared)

So now find the square root of 296 to get c= = 2 = 17.20465053

Round it to 2 significant figures= 17 cm (units weren't specified, so I've just put cm)

B-

Using the same equation-   + =

+ =

= 4 + = 16 (Take away the 4)

= = 12 (Find the square root)

= b = = 2 = 3.464101615

Simplify to 1 Significant figure (I'm guessing since the other values are 1 digit long) = 3 cm (whichever unit you wanna use)

C-

  + =  =   + =

= 100 + 576 = 676

Find the square root of 676 which = = 26cm exactly

D-

+ =  =   + =

= 25 + 36 = 61

= 7.810249676

Round so 1 S.F = 8 miles

E-

+ =  =  36 + = 64

= = 28

Find the square root= = 5.291502622 = 5cm

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
