Let’s use a random equation
(3x-7)(6x+2)
the F stands for “first”... the 3x is first in its parenthesis. The 6x is the first in its parenthesis. So multiply those. You get 18x^2
The O stand for “outer” the 3x and 2 are the outer. They equal 6x.
the I stand for “inner”. -7 and 6x are the inner parts of the equation. They equal -42x
The L stand for last. The last are -7 and 2. They equal-14.
Put it all together
18x^2+6x-42x-14
18x^2-36x-14

Answer:
m = 11, and the correct equation is m + 7.28 = 18.28
Step-by-step explanation:
First, we need to solve:
0.2*m = 2.20
To do it, we need to divide by 0.2 in both sides:
0.2*m/0.2 = 2.20/0.2
m*(0.2/0.2) = 11
m = 11
Ok, we know the value of m.
Now we need to input the value of m in each one of these 4 equations and see which one is the correct one.
The correct equation is;
m + 7.28 = 18.28
When we replace m by 11, we get:
11 + 7.28 = 18.28
So the equation is correct.

How come two negatives make a positive, but three negatives makes a negative? Does this have to do with there being an odd/even amounts of negatives and cancelling each other out?
Answers
Okay well work step by step. If there is three negatives, you first want to multiply the first two negatives. Your number will come out positive but you are still left with one more negative. so you will multiply the positive number with the negative number which comes out with a negative number.

Answers
Answer:
A, B, C
Step-by-step explanation:

Answer:
B. 12 + 0.25 ⋅ 12
C. 12(1 + 0.25)
Step-by-step explanation:
It asks you how far she walks all together, so you need to find that answer first to figure out the rest correctly. Now, the total she walked is 15 miles. B. and C. give you 15, however, the rest give you different answer than the total she actually walked.

Mark wants to make an enclosure for his cows.
He has 44 metres of fencing.
He wants the width to be 8 metres less than the length.
What dimensions should the field have?
?
Answers
Answer:
the length and width be 15 meters and 7 meters respectively
Step-by-step explanation:
The computation of the dimension of the field is given below;
Let us assume the fencing be p
Length be x
And, the width be x - 8
So,
P = 44
P = x - 8 + x - 8 + x + x
= 4x - 16
Now
4x - 16 = 44
4x = 44 + 16
4x = 60
x = 15
And, the width be 15 - 8 = 7
So, the length and width be 15 meters and 7 meters respectively

2x = -7 ## ^ Subtraction POE
x = -3.5 ## ^ Division POE
Answer:
X=0
Step-by-step explanation:
Use PEMDAS to get rid of some things. Do 3 x 2 = 6. Then distribute the like terms to one side seperating 2x and "0": +1 ---> 0-1 = -1. Now divide... 2x/2 = x (cancels out) and 0/2 = 0. Therefore X=0. But I'm not a computer so double check your answer.

David and his 2 children are going to the zoo.
The administration price is
Adult:£60
Children:£67
FAMILY DISCOUND CARD GIVES
1/5 off adults price
60% off child price
Work out the total price David pays after using his discount card.
Answers
Answer:
£92.40
Step-by-step explanation:
Discount price for David =1/5 of 60
= 1/5 × 60/1
= £12 (5 multiplied by 12 is 60)
Price for one child = £67
Price for 2 children= £67 × 2
= 134
Therefore discount price for the children,
134 × 60/100
= 134 × 6/10
= 134 × 3/5
= 26.8 × 3
= 80.4
= £80.40
Therefore total Price David pays,
£80.40 + £12
= £92.40

Find the equation of the line: which passes through (1,-7) and is perpendicular to (-4,6) and (5,-3)
Answers
Answer:
-9 6 that is because the line has to be perpenducular to the other line
Step-by-step explanation:
Slope of line between points (-4, 6) and (5, -3)
=> Rise / Run
=> [6 - (-3)] / [(-4) - 5]
= 9 / (-9)
= -1.
Thus slope of perpendicular line
= -1 / (-1) = 1.
We have y = x + c.
When x = 1, y = -7.
=> (-7) = (1) + c, c = -8.
Hence y = x - 8.
