Answer:
m = 5, n = 2
Step-by-step explanation:
B is the correct answer.
We are adding the border of x thickness to all 4 sides of the table. This makes the new width of the table 36+x+x = 36+2x and the new length of the table 72+x+x=72+2x. To find the area, we multiply the length and width:
(36+2x)(72+2x) = 3006
Multiplying the binomials, we get:
36*72 + 36*2x + 2x*72 + 2x*2x = 3006
2592 + 72x + 144x + 4x² = 3006
Combining like terms gets us
2592 + 216x + 4x² = 3006
Subtract 3006 from both sides:
2592 + 216x + 4x² - 3006 = 3006 - 3006
-414 + 216x + 4x² = 0
Writing in standard form we have
4x²+216x-414=0
Answer:
32
Step-by-step explanation:
I'll assume they're vertical angles
5x - 13 = 2x + 14
3x = 27
x = 9
<ABC:
5x - 13
5(9) - 13
32
First you should write what you know since we don't know how many helmets we will use x
helmets - 5(x)
bats - 3(6x)
then write out the equation
5(x)+3(6x)=4600
then solve so first multiple 5 times x and multiply 3 and 6x
5x+18x=4600
then combine like terms which are 5x and 18x
23x=4600
then divide both sides by 23
x=200
200is the number of helmets and since there are six times the bats as helmets you multiply that by six and get
helmets=200
bats=1200
