Help Me Please, Which Postulate Proves These Two Triangles Are Congruent?

Answers

Answer 1

Answer:

C

Step-by-step explanation:

These triangles do look congruent. However, in fact, we don’t have enough information. We need 3 parts of a trainable to be shown congruent for it to be congruent, including HL congruence (because this requires a right angle). In the diagram, only 2 sides are shown to be congruent. This isn’t enough information to prove that the triangles are congruent. Therefore, it is C.

I hope this helps! :)

4x^3 + 7x^2 +4x + 7

Answers

(4x+7) (x^2+1) is it factored

The common factor is x ^ 3

So that gives you x ^ 3 = (4+ 7  / x + 4 / x ^ 2 + 7 / x ^ 3)

Because we therefore simplify x ^ 3 = (4 + (7x ^ 2 / x ^ 3) + (4x / x ^ 3) + 7 / x ^ 3)

2.) Use what you know about similarity in right triangles to solve this problem.
Given the area of a triangle is ½ bh, find the area of triangles ABC, BDC and DCA. The picture of the question is right below! thank you.

Answers

Answer:

ABC  2.44

BDC  1.22

DCA  1.22

Step-by-step explanation:

area of a triangle=bh1/2

to find height, use pythagorean theorem a^2 + b^2 =c^2

for ABC, height (1.95) times base(2.5) divided by 2

ABC is bisected so DCA and BDC are congruent, meaning once you've found the area of one of those triangles, you have found both areas.

Cut 2.5 in half to find the base of BDC/DCA.

base (1.25) times height (1.95) = 1.22

Answer:

ABC  2.44

BDC  1.22

DCA  1.22

In ΔDEF, if DE ≅ DF and EF is the hypotenuse, then ΔDEF is
a acute and scalene. c. right and isosceles.
b right and scalene. d. obtuse and isosceles.

Answers

Answer:

C. Right and isosceles

Explanation:

Since two sides of the triangle are equal in length ([tex]DE[/tex] and [tex]DF[/tex]), this means that the triangle is an isosceles triangle. Since [tex]EF[/tex] is the hypotenuse of this triangle, it also means that the triangle is a right-angle triangle (the hypotenuse refers to the longest side of a right triangle). Therefore, we can conclude that ΔDEF is right and isosceles.

Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio.

A(-6, 9), B(2, 1); Ratio 5 to 3

Answers

Answer:

The coordinates of the point P = (x, y) = (-1, 4)

Step-by-step explanation:

Let the coordinates of P be (x, y)

(x₁, y₁) = (-6, 9)(x₂, y₂) = (2, 1)ratio = m:n = 5:3

Using the section formula

x = [(mx₂ + nx₁)] / [(m+n)]

   = [5(2)+3(-6)] / [5+3]

   = [10-18] / [8]

   = -8/8

    = -1

y = [(my₂ + ny₁)] / [(m+n)]

   = [5(1)+3(9)] / [5+3]

   = [5+27] / [8]

   = 32/8

    = 4

Therefore, the coordinates of the point P = (x, y) = (-1, 4)

Answers

Answer:

g(x) = (x-8)^2 - 5

Step-by-step explanation:

subtracting from x inside of the square translates the function to the right and adding to x inside of the square translates it to the left.

(x-8)^2 - 1  translates the function 8 units to the right

subtracting from the constant translates the function down and adding translates it up.

x^2 - 5 translates the function 4 units down

Therefore, (x-8)^2 - 5 translates the function 8 units to the right and 4 units down

you can multiply the number of cookies with the cost of each box

Step-by-step explanation:

60 (number of boxes) x 3.50 (the cost for each box) = $210

42 (number of boxes) x 3.50 (the cost for each box) = $147

56 (number of boxes) x 3.50 (the cost for each box) = $196

Answers

Step-by-step explanation:

Length on model : Length on actual = 1 : 25

=> Area on model : Area on actual

= 1² : 25² = 1 : 625.

Therefore area on model = 300ft² * (1/625) = 0.48ft².
