Dean needs 60 inches of wood to build a rectangular picture frame. The length, l, of the frame is twice its width, w. Three of t
1 answer:
Option A,B and C are correct.
Step-by-step explanation:
Perimeter = 60 inches
Width = w
length = 2w
Finding the equation:
The formula of perimeter of rectangle is:
Putting values:
So, the options that give the correct value of w are:
2.(2w+w) = 60 Simplifying: 4w+2w=60
w+2w+w+2w=60 Simplifying: 4w+2w=60
2⋅w+2⋅2w=60 Simplifying: 4w+2w=60
The last Option w+2w=60 is incorrect.
So, Option A,B and C are correct.

Answer:
y = - x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = =
= -
Since the line crosses the y- axis at (0, 6) ⇒ b = 6
y = - x + 6 ← equation of line
Given:
w be the weight in pounds of a baby tigers.
To find:
The inequality if baby tigers can be no larger than 4 pounds.
Solution:
Baby tigers can be no larger than 4 pounds. It mean weight of baby tigers cannot be greater than 4. In other words, the weight of the baby tigers must be less than or equal to 4.
Let w represents weight in pounds and the weight of the baby tigers must be less than or equal to 4. So,
Therefore, the required inequality is .
