Answer:

31

Step-by-step explanation:

ABC has a perimeter of 23, so

   AB + BC + AC = 23

The perimeter of ABE would be the sum of these sides:

  AB + BC + CD + DE + AE

We also know:

  AE = AC, CD=4 and DE=4 because ACD is congruent to AED

So, AB + BC + CD + DE + AE = AB + BC + 4 + 4+ AC = 23+8 = 31

Solve for w pls help thank u

Answer:

w = -19

Step-by-step explanation:

-6w + 4(w +3) = 26

-6w + 4w + 12 = 26

simplify

-2w + 12 = 26

now get the variable and the numbers on different sides

-2w + 12 - 12 = -2w

26 + 12 = 38

-2w = 38

now divide each side by -2

-2w / -2 = w

38 / -2 = -19

w = -19

Step by step how to factor:<br> 2y^2+9y+9=0
weeeeeb [17]
Use ac method
for ax²+bx+c=0 when a≠1


multiply a and c, let's call the product r
what 2 numbesr multiply to get r and add to get b


2y²+9y+9=0
2*9=18
wat 2 numbers multiply to get 18 and add to get 9
3 and 6
split it up to that

2y²+3y+6y+9=0
group
(2y²+3y)+(6y+9)=0
factor
y(2y+3)+3(2y+3)=0
undistribute
(y+3)(2y+3)=0
set to zero

y+3=0
y=-3

2y+3=0
2y=-3
y=-3/2


y=-3 and -3/2
it's factored form is (x+3)(2x+3)

"Find the missing side lengths in each pair of similar figures." Someone explain please
Lana71 [14]
AB is proportional to XY since they are similar triangles making it 25:10 or 5:2
so then AC:XZ  would be 5x:2x and 5x:6 so then its 15:6 since x is 3 basically set up proportions and so value of the big triangle to the small triangle would be at rails os 5:2
