Answer:
5b + 9
Step-by-step explanation:
You are essentially trying to simplify the expression given to you. To do so, combine terms with like terms:
4b + 9 + b
In this case, combine all terms with the same amount of variables, b.
(4b + b) + 9 = 5b + 9
5b + 9 is your answer.

Answer:
504
Step-by-step explanation:
The area of the base is 14 x 14 which is 196
The area of one triangle is 1/2 x base length x height which is:
1/2 x 14 x 11 = 77
So the area of one triangle is 77. The area of all the triangles is the same and there are 4 triangles.
So the surface area is
196 + 77 + 77 + 77 + 77 = 504
I think that 22=4. please don't be mad if in wrong.
Let one number be x and the other number be y.
The 2 equations are:
x - y = 0.6 --------------- (1)
x/y = 0.6 --------------- (2)
From equation (1):
x - y = 0.6
x = 0.6 + y --------------- Sub into (2)

0.6 + y= 0.6y
y - 0.6y = - 0.6
0.4y = - 0.6
y = -0.6 ÷ 0.4
y = -1.5
Sub y = -1.5 into (1):
x - y = 0.6
x - (-1.5) = 0.6
x + 1.5 = 0.6
x = 0.6 - 1.5
x = - 0.9
Answer: The numbers are -0.9 and -1.5
Answer:
the answer is 2
Step-by-step explanation:
y=-6x+19
-6x+4y=16
-6x+4(-6x+19)=16
-6x-24x+76=16
-30x+76=16
-30x=16-76
-30x=-60
if there is - in both side we should cut them
30x=60
x=60/30
x=2
