Yes, because it still have 3 sides.
Answer:
Step-by-step explanation:
<u>Polynomial Factoring</u>
The volume of a cardboard box is expressed as:
It's required to factor that expression.
First, factor out 3:
The expression in parentheses is a perfect square:
Answer:
x = students
y = adults
Linear Systems of Equations :
x + y = 937
0.75x + 2y = 1,109
Step-by-step explanation:
Step 1 : eliminate one of the variables
x + y = 937
0.75x + 2y = 1,109
-2(x + y = 937) = -2x - 2y = -1874
-2x - 2y = -1874
0.75x + 2y = 1109
We can eliminate y since -2y + 2y = 0
Step 2: Find x number of students.
-2x = -1874
+0.75x = 1109
____________
-1.25x = -765
____________ = 612 students attended
-1.25
937 - 612 = 325 adults
Check Answer :
612 x 0.75 = $459
325 x 2 = $650
$650 + $459 = $1,109
Therefore, there will be 612 students attending and 325 adults.
Answer: The smaller integer is 12, while larger integer is 23
Step-by-step explanation:
The sum of two positive integer;
a + b = 35, when smaller integer is subtracted from twice the larger integer we have, 2a - b = 34 assuming b as the smaller integer, so your equation goes this way.
a + b = 35........(1)
2a - b = 34.......(2). To solve by elimination method add both equation. We have;
3a + 0 = 69
3a = 69, divide both sides by 3.
3a/3 = 69/3 so we have;
a = 23
To know the value of b, substitute 23 for the value of a in any of the equations, let's go with (1). From one we have;
a + b = 35 if a = 23 we have;
23 + b = 35
b = 35 - 23
b = 12.
Check: a + b = 35
23 + 12 = 35
35 = 35
The answer is correct.
