Which expression is equivalent to 21 + 49?A 7(3 + 49)

B 7(3 + 7)

C 7(14 + 42)

D 7(14 + 49)

Answers

It would be the second choice, B. 7(3+7) because when you distribute, you get 21+49, because 7x3=21 and 7x7=49.

the answer would be b because 3+7 is 10 and multiple that by 7 is 70. and 20 plus 49 is 70

State whether the equation is a linear equation in one variable or not. –2x(–2 – x) = x + 1

Answers

If you'll simplify this equation -2x(-2-x)=x+1
you'll get 4x+2x²=x+1
simplify further 2x²+3x-1
this one looks like a quadratic equation.
Thus, this is not a linear equation,

$-2x(-2 -x) = x + 1\n 4x+2x^2=x+1$

It's not linear. It's quadratic.

ΔABC is reflected across line L to form Δ ALBLCL, and intersects line L at point D. Which equation is not necessarily true?

Answers

option 2
ALD=BLD equation is not necessarily true, all other remaining equations satisfy laws of reflection.

Answer:

$A_LD= B_LD$ is false statement.

B is correct

Step-by-step explanation:

$\triangle ABC$ is reflected across line L to form $\triangle A_LB_LC_L$ .

If we join A and $A_L$ and intersect line L at point D.

Reflection: A transformation of a geometric figure such that creating a mirror image across the line. The line of reflection is called axis of reflection.

As we know mirror image figure has same property their side measure and angle measure equal.

$\triangle ABC \text{ is congruent to }\triangle A_LB_LC_L$ .

Distance of each vertex of figure from axis of reflection line is equal to their corresponding vertex.

Therefore, True statements are:-

$AD=A_LD$

$\angle ACB=\angle A_LC_LB_L$

$\angle BAC=\angle B_LA_LC_L$

$A_LD\neq B_LD$

Please find the attached figure for reflection and coordinates.

Hence, $A_LD= B_LD$ is false statement.

A carrot has been squared off. It is now 4 inches long and 1 inch thick. You need to cut it into medium dice. About how many individual diced squares will the carrot produce?

Answers

Final answer:

To determine the number of diced squares a carrot will produce, calculate the volume of the carrot and divide it by the volume of each diced square. In this case, the carrot produces 4 individual diced squares.

Explanation:

To determine the number of individual diced squares the carrot will produce, we need to calculate the volume of the carrot and divide it by the volume of each diced square. The volume of the carrot is found by multiplying its length, width, and height. In this case, the length of the carrot is 4 inches and the width and height are both 1 inch. Therefore, the volume of the carrot is 4 x 1 x 1 = 4 cubic inches.

Next, we need to determine the volume of each diced square. A diced square can be considered a cube, where all sides have the same length. In this case, since the carrot has been squared off, the length, width, and height of the diced square are all 1 inch.

To calculate the volume of the diced square/cube, we simply multiply the length, width, and height together. In this case, 1 x 1 x 1 = 1 cubic inch.

Finally, we can find the number of individual diced squares the carrot will produce by dividing the volume of the carrot by the volume of each diced square. 4 cubic inches / 1 cubic inch = 4 individual diced squares.
