Answer:
8 inches
Step-by-step explanation:
You want to find the width (w) in inches such that ...
V = LWH
2720 = (2w+4)·w·17 . . . . . . . . . . fill in the given values
80 = (w+2)(w) = w^2 + 2w . . . . . divide by 34
81 = (w +1)^2 . . . . . . . . . . . . . . . . complete the square
9 = w+1 . . . . . . square root (we only care about the positive solution)
8 = w . . . . . . . . subtract 1
The width of the box is 8 inches.
Answer:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 1/6x from both sides.
Step 3: Subtract 1/12 from both sides.
Step 4: Multiply both sides by 12.
Answer:
x=2
plz mark brainliest :)
Well i ll give u some tips
1-u should know the formulas for calculating different objects areas
2-find the length of their sides or diagonals(which are needed on the formula)
3-calculate the area
for example the triangle on the picture
1-s=leg1*leg2/2
2-the length of:leg1=10-3=7,,leg2=7-1=6
3-s=7*6/2=21
Answer:
x= -b/2a
Step-by-step explanation:
hello :
y = ax²+bx+c .... (a≠0)
the equation of the axis of symmetry of this graph is : x= -b/2a
