Answer:

x=25

6x-45=6×25-45=105

4x+5=4×25+5=105

Step-by-step explanation:

6x-45=4x+5(Reason:- vertically opposite angle)

or, 6x-4x=45+5

or,2x=50

or,x=25

Answer:

6x-45°=4x+5°(vertically opposite angles are equal)

6x-4x=5+45

2x=50

x=50/2

x=25

It's D. Factor x^3 out of the denominator leaving 1 - 5x, then cancel out the x^3 in the numerator with the one you factored out of the denominator. That leaves you with 1 - 5x cannot equal 0. Solve that for x and you get 1/5. However, since we are talking vertical asymptotes and the x^3 is a removable discontinuity, we have to count it as a "problem". Therefore, the other value of x that is not allowed is x = 0.

12 cups.

If she made 4 batches then it would be 12 cups of orange, and 20 cups of pineapple which adds to 32.

Answer

5. ΔABC ≅ ΔDEF is true.

6. ΔABC ≅ ΔGHI is not true.

Step by step explanation

5. Find the lengths of the triangle ABC.

BC = 3

Use the distance formula to find the length of AB and AC

Distance formula = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

Coordinates of A = (1, 4) and B = (2, 2).

Now plug in these values in to the distance formula.

AB = $\sqrt{(2 -1)^2 + (2 - 4)^2} \\$

AB = $\sqrt{(1)^1 + (-2)^2}$

AB = √1 + 4

AB = √5

Now let's find the length of AC.

A = (1, 4), C = (5, 2)

Use the distance formula and the length of AC.

AC = $\sqrt{(5 - 1)^2 +(2 - 4)^2}$

AC = $\sqrt{(4)^2 + (-2)^2}$

AC = √(16 + 4)

AC = √20

Now let's find the length of GI

G = (6, 6) and I = (8, 1)

Use the distance formula.

GI = √(2)^2 + (-5)^2

GI = √(4 + 25)

GI = √29.

The length of EF = 3, DE = √5, EF = √20

Now let's compare the two triangles ABC and DEF.

The sides of the triangle ABC is equal to the sides of the triangle DEF

By SSS property, ΔABC ≅ ΔDEF.

6) The side length of GI = √29 which is not equal to the side length of AC = √20.

Therefore, the ΔABC ≅ ΔGHI is not true.

Hope this will help you.

Thank you.

Help asap ill give brainliest

DaniilM [7]

Answer :

This figure consists of two shapes that are a rectangle and a square . We will first find the area of rectangle then the square then add them . Let's work on this together ,

Breadth of rectangle = 4 cm
Length of rectangle = 4 + 5 + 3
Length = 12 cm
Area of rectangle = 12 × 4
48 cm²

Area of square ,

Side × Side
5 × 5
25 cm²

Total area of the figure ,

48 + 25
73 cm²
