Answer:
5/3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Using FOIL (First, outer, inner, last)
First, we multiply 3x and x to get 
(First)
We then multiply 3x and 1 to get 
(outer)
Then 4 and x to get 
(Inner)
Then multiply 1 and 4 to get 
(last)
Since the quadratics are all positive, we add all the terms together to get:
. Since 3x and 4x are like terms, we add them together and simplify to get:
And since we can't simplify any further, that's our answer!
Hope this helps :D
Answer:
86
Step-by-step explanation:
the rectangle portion is 18*4= 72
1 triangle portion is 1/2bh where the base is 4 and height is 3.5
1/2*14=7
the 2nd triangle as the same proportions, so it is also 7
72+7+7=86
Answer:
{x,y} = {2,3}
Step-by-step explanation:
// Solve equation [2] for the variable x
[2] x = -2y + 8
// Plug this in for variable x in equation [1]
[1] 4•(-2y+8) - y = 5
[1] - 9y = -27
// Solve equation [1] for the variable y
[1] 9y = 27
[1] y = 3
// By now we know this much :
x = -2y+8
y = 3
// Use the y value to solve for x
x = -2(3)+8 = 2
