Answer:
Проведите линию через форму, чтобы каждая сторона была зеркальным отражением. Когда фигура складывается пополам по оси симметрии, две половинки совпадают. На этой фотографии белая линия по центру представляет собой вертикальную ось симметрии.

Answer:
21, 22, and 23
Step-by-step explanation:
Three consecutive natural numbers can be represented as n, n+1, and n+2.
The square of the smallest number would be
and its equal to the product of the other two (n+1)(n+2).
So the equation is
.
If n is 21 then the next numbers are 22 and 23.
To answer your question Simplifying<span>8(5m + 10) = 0
Reorder the terms:
8(10 + 5m) = 0
(10 * 8 + 5m * 8) = 0
(80 + 40m) = 0
Solving
80 + 40m = 0
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-80' to each side of the equation.
80 + -80 + 40m = 0 + -80
Combine like terms: 80 + -80 = 0
0 + 40m = 0 + -80
40m = 0 + -80
Combine like terms: 0 + -80 = -80
40m = -80
Divide each side by '40'.
m = -2
Simplifying
m = -2 your welcome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!</span>
Answer:
The purpose of this task is to help students see the connection between a÷b and ab in a particular concrete example. The relationship between the division problem 3÷8 and the fraction 38 is actually very subtle.
3÷8 is the number you multiply 8 by to get 3.
38 is the number you get by taking 3 copies of the unit fraction 18.
So 3÷8 is defined in terms of multiplication, and 38 is defined in terms of unit fractions. It is not obvious that these two numbers are the same, so students need opportunities to see that they will necessarily always be the same. Note that if b people share a pies equally, then each person will get ab of a pie by the same kind of reasoning shown in the solution below.
This task is probably best suited for instruction or formative assessment.
