Given below, the arcs AB and CD must be congruent.

artcher [175]

Answer:

It is true.

Step-by-step explanation:

The equation for arc length is theta, in radians, multiplied by the radius. In the image, the angles in degrees are same. So, the angle in radians must also be same. So, multiplying both with radius will give the same value of arc length. They are congruent.

Mrs. Lang is 4 times as old as her daughter Jill. The sum of their ages is 60 years. Set up the two equations that can be used t

KatRina [158]

Answer:

The two equations that can be used to find each of their ages are $x=4 \times y$ and $x+y=60$ .

Step-by-step explanation:

We are given that Mrs. Lang is 4 times as old as her daughter Jill. The sum of their ages is 60 years.

Let the age of Mrs. Lang be 'x years' and the age of her daughter Jill be 'y years'.

Now, according to the question;

The <u>first condition</u> states that Mrs. Lang is 4 times as old as her daughter Jill, that means;

$x=4 \times y$ ----------------- [equation 1]

The <u>second condition</u> states that the sum of their ages is 60 years, that means;

$x+y=60$

$4y + y = 60$ {using equation 1}

$5y=60$

$y=\frac{60}{5}$

y = 12 years

Now, putting the value of y in equation 1 we get;

$x=4 \times y$

$x= 4 \times 12$ = 48 years

Hence, the age of Mrs. Lang is 48 years and her daughter Jill is 12 years old.

Answer:

21. 3x^2 +7x

22. 6x^3 +3x

Step-by-step explanation:

21. The perimeter is the sum of the side lengths.

P = (x^2 +3x +1) +(4x -1) +(2x^2)

P = x^2(1 +2) +x(3 +4) +(1 -1) . . . . combine like terms

P = 3x^2 +7x

__

22. The area is the product of the dimensions.

A = (3x)(2x^2 +1)

A = 6x^3 +3x . . . . . use the distributive property
