Answer:
3x²+9x+8
Step-by-step explanation:
x²+x+x(x+2)+1(x+2)+x(x+3)+2(x+3)
x²+x+x²+2x+x+2+x²+3x+2x+6
x²+x²+x²+x+2x+x+3x+2x+2+6
3x²+9x+8
Answer:
555.94
Step-by-step explanation:
16 x 11 = 176/2
88
since there are two of the same triangle
88 x 2
176
11 is the radius
A = 
A = 3.14 ( pie is 3.14, if not then pi) x (11x11)
A = 3.14 x 121 (or 121)
A = 379.94
379.94 + 176 (or 121pi + 176)
555.94

You have 10 slices of cake, you and your friends Jerry, George, Martha, and Jenny ( just an example ) eat 2 slices of cake.
A more real life one would be:
You have 6 bills to pay off, then two more come in, you only pay off 4,

Answer:
part 1 : y = x^2 + 3x + 5
y = x + 13
solution:
x^2 + 3x + 5 = x + 13
x^2 + 2x -8 = 0
(x+4)(x-2) = 0
x = -4 or x = 2
if x = -4, y = 9
if x = 2 , y = 15
part 2 : x^2 + 2x + 1 = 0
(x + 1)^2 = 0
x = -1
y = 1
task 2
part 1 : Let our two digit number be 26
Next, we rewrite it as a difference of two numbers
26=32-6
We want to square 26 using the identity:
In this case,
x=32
y=6
Substituting into the identity
