Answer:
Length = 45.37 in
Width = 30.56 in
Step-by-step explanation:
Let the width of the picture be 'w' inches.
Given:
Perimeter of the picture is, 
Length is 15.75 inches shorter than twice the width. So, length is:
Now, we know that the perimeter of a rectangular shape is given as the sum of all of its side. So, the picture is also of rectangular shape and hence the perimeter is given as:
Plug in the values of 'l' and 'P' and solve for 'w'. This gives,
Therefore, the width of the rectangular picture is 30.56 inches.
Length of the picture is, 
So, length of the picture is 45.37 inches and width is 30.56 inches.
Answer:
x < 3
Step-by-step explanation:
−4x − 8 > −20
Add 8 to both sides.
-4x > -12
Divide both sides by -4. Remember that when you multiply or divide both sides of an inequality by a negative number, the direction of the inequality sign changes.
-4x/(-4) < -12/(-4)
x < 3
Answer:
The answer is B.
Step-by-step explanation:
It is given that the formule of volume of prism is V = a × h where a stands for area of cross-section. Then, substitute the following value into the formula :
V = 864 in³
h = 18 in
a = ?
864 = a × 18
Next, you have to make a as the subject by dividing 18 on both sides :
864 ÷ 18 = a × 18 ÷ 18
48 = a
a = 48 in²
