A trapezoid has two parallel sides, but the top one is shorter than the bottom one
Answer:
x=-2
Step-by-step explanation:
-4x – 6(3x + 4) = -4 + 8(1 - x)
Distribute
-4x – 18x -24 = -4 + 8 -8x
Combine like terms
-22x -24 = 4-8x
Add 22x to each side
-22x+22x -24 = 4-8x+22x
-24 =4+14x
Subtract 4 from each side
-24-4 = 4+14x-4
-28 = 14x
Divide each side by 14
-28/14 =14/14
-2 =x
(I'm assuming the first term is 10 b squared)
The first thing you need to know before diving in is to find the factors of 10 and 3.
10 = 1x10, 2x5
3 = 1x3
Next you will have to find a combination that when multiplied the middle term is 17. In this case it is 2x5 and 1x3. We can test it out by setting it up in binomials.
(2b + 3)(5b + 1) = 10b squared + 2b + 15b + 3 = 10b squared + 17b + 3.
The reason why the binomials are additions is because both the middle and end terms are positive.
Hope this helps!
Answer:
$2.64
Step-by-step explanation:
9 coins are pennies (reply to my comment if you want to know how I got it)
19 coins are dimes (reply to my comment if you want to know how I got it)
9 (pennies) + 4 = 13 (nickels)
$1.90 (dimes) + $0.09 (pennies) + $0.65 (nickels) = $2.64
Answer:
C
Step-by-step explanation:
a is incorrect because X is positive
b is incorrect because the > signs are wrong
d is incorrect because it is x-1 and x-2 not x+1 and x+2
