Answer:
<h2>6</h2>
Step-by-step explanation:
Substitute 2 for z in the given equation
Follow the PEMDAS order of operations
A, and b are correct. c could be but, it is not summer all over the world. for d it is Boston, Massachusetts (city,state)

Multiply2 * x/15 to 2x/15
multiply both sides by 30 which is the LCM of 10, 5, 3, and 15
expand it
simplify 18 - 15x - 12x - 6 + 10x to 12 - 17x
add 17x to both sides
add 4x + 17x to = 21x
divide both sides by 21
simplify 12/21 to 4/7
now simplify
Answer: x = 4/7.
Answer:
Area = length * width
112 = (2w+2)*w
112 = 2w^2 + 2w
0 =2w^2 + 2w - 112
0 = w^2 + w - 56
0 = ( w + 8 )( w - 7 )
w+8=0 results in negative measures
w-7=0 --> w = 7
width is 7
length is 16
Answer:
surface area of rectangle= 2[(l+w) +(l+h). +(w+h)]
