Work out the lengths of side a and side b 8cm and 5 cm 1 triangle 17cm and 12 cm on the other triangle pythagoras
Viktor [21]

Answer:

a = 9.4 cm

b = 12.0 cm

Step-by-step explanation:

Check the image uploaded for diagram;

For the first diagram, side length a is calculated as follows;

a² = 8²  +  5²

a² = 64  +  25

a² = 89

a = √89

a = 9.4 cm ( approximated to 1 decimal place)

For the second diagram, side length b is calculated as follows;

b² = 17²  -  12²

b² = 145

b = √145

b = 12.0 cm (approximated to 1 decimal place)

What is the inverse of f(x)= √3x+4 -1? (The -1 is separate and not part of the square root) √3x+4
icang [17]

Answer:

y=(x^2 -2x-3)/3

Step-by-step explanation:

f(x)= √3x+4 -1

x=√3y+4 -1

(x+1)^2=(√3y+4)^2

3y+4=x^2 +2x+1

3y=x^2 +2x-3

y=(x^2 +2x-3)/3

Factor the expression. 4d + 12 Enter your answers in the boxes.
Dmitry_Shevchenko [17]
4d + 12 = 4(d + 3)
Basically, you just need to determine what 4d and 12 have in common.  In this case, they both divide evenly by 4. Therefore 4 (d + 3) = 4d + 12 according to the distributive property.
