Answer:

4.5

Step-by-step explanation:

42-9=33              (9÷2=4.5)

33÷2=16.5

16.5-4.5=12

16.5+16.5+4.5+4.5=42

length=16.5

width=4.5

To prove a similarity of a triangle, we use angles or sides.

In this case we use angles to prove

∠ACB = ∠AED (Corresponding ∠s)
∠AED = ∠FDE (Alternate ∠s)

∠ABC = ∠ADE (Corresponding ∠s)
∠ADE = ∠FED (Alternate ∠s)

∠BAC = ∠EFD (sum of ∠s in a triangle)

Now we know the similarity in the triangles.

But it is necessary to write the similar triangle according to how the question ask.

The question asks " ∆ABC is similar to ∆____. " So we find ∠ABC in the prove.

∠ABC corressponds to ∠FED as stated above.
∴ ∆ABC is similar to ∆FED

Similarly, if the question asks " ∆ACB is similar to ∆____. "
We answer as ∆ACB is similar to ∆FDE.

Answer is ∆ABC is similar to ∆FED.

gtnhenbr [62]

Answer:

I think the correct answer from the choices listed above is the last option. The range of the rejected bags, x, for the bags of flour. A bag of flour is said to  weigh within 3.2 grams in order to be accepted. Therefore, it should weigh within 746.8 to 753.2 grams. Outside that range is rejected.

In what interval is the function f(x)=squareroot x^2+5x+4 defined
KatRina [158]

9514 1404 393

Answer:

  (-∞, -4] U [-1, ∞)

Step-by-step explanation:

The quadratic expression factors as ...

  x^2 +5x +4 = (x +4)(x +1)

The zeros of this expression are where these factors are zero, at x=-4 and x=-1. The product is negative when one factor is negative and the other is positive, in the region -4 < x < -1. It is non-negative elsewhere. f(x) is defined where the quadratic is not negative, on the union of intervals ...

  (-∞, -4] U [-1, ∞)
