Answer:
1450 cm
Step-by-step explanation:
A cardboard box is shaped like a rectangular prism.
To solve the above question, we apply the formula for Surface Area of a Rectangular Prism
A=2(wl+hl+hw)
Where
w = width = 5cm
I = length = 25cm
h = height = 20 cm
=2 × (5×25+20×25+20×5)
= 2(125 + 500 + 100)
= 2(725)
=1450 cm of cardboard material should be used.

Paisley set up the following equation to solve a math problem: 33 + 57 + x = 180. What could the x represent?
I NEED HELP PLEASE!!!
Which symbol makes the statement true?-2x> or equal to 16 so x ? -8
Given:
The inequality is
[tex]-2x\geq 16[/tex]
To find:
The correct symbol for the inequality x __ -8.
Solution:
We have,
[tex]-2x\geq 16[/tex]
When we divide or multiply an inequality by a negative number, then we need to change the sign of inequality.
Divide the given inequality by -2.
[tex]\dfrac{-2x}{-2}\leq \dfrac{16}{-2}[/tex]
[tex]x\leq -8[/tex]
The correct symbol for the blank is ≤.
Therefore, the correct option is J.

What's 7/81 rounded to the nearest tenth?
Answer:
Did you mean 7.81 'cause if so-
the rounded answer would be 8.0
Step-by-step explanation:
in the figure below,two lines are parallel and m < 1 =83°. Find all other angles
Answer:
angle 3=83(vertically opposite angles are equal)
angle 5=angle 3(alternate interior angles) so = 83
angle 7 =angle 5 ( vertically opposite angles)
angle 2 +angle 1=180 (linear pair ) so angle 1 + 180-83=97
angle 4 = angle 2 (VOA)=97
angle 6 =angle 4 (AIA)=97
angle 8 =angle 6(VOA)=97

How many root(s) does the following equation have? Explain how you know for credit.
-6x2 - 6x + 7 = 7
Answer:
This equation has two roots. We know this because of the format it is in. Any expression in the form ax² + bx + c is a quadratic one, which describes a parabola and has two roots.
In this case, the roots are -1 and 0.
Step-by-step explanation:
Let's see if we can find those values:
-6x² - 6x + 7 = 7
-6x² - 6x = 0
x² + x = 0
x(x + 1) = 0
x = -1, 0
We could also run through solving this by completing the square:
-6x² - 6x + 7 = 7
-6x² - 6x = 0
x² + x = 0
x² + x + 0.25 = 0.25
(x + .5)² = 0.25
x + .5 = ±√0.25
x + .5 = ± 0.5
x = -0.5 ± 0.5
x = -1, 0

The length of a rectangle is repesented by (5×-3) and the width is repesented by (2×-1) write an expression for the perimeter of the rectangle
Answer: The expression for the perimeter of the rectangle =14x-8.
Step-by-step explanation:
Given: Expression for length of rectangle = 5x-3
Expression for width of rectangle = 2x-1
We know that,
Perimeter of rectangle = 2 (length + width)
Then, perimeter of rectangle = 2(5x-3+2x-1)
= 2(5x+2x-3-1) [Combine like terms]
= 2 (7x-4)
= 14x -8
Hence, the expression for the perimeter of the rectangle = 14x-8
