Solutions
We know that a rectangle has four sides and the perimeter of a rectangle is the distance around the outside of the rectangle.The opposite sides of a rectangle are congruent To find the perimeter you have to use the formula 2 × <span>(Side A + Side B).
</span>
We have the side lengths 7.7 mm and 17.2 mm.
Solve
2 × <span>(Side A + Side B)
2 </span>× <span>( Side A (7.7) + Side B (17.2) )
</span>= (7.7 x 2) + (17.2 x 2)
= 49.6
<span>The perimeter is 49.6 mm². </span>

Explicación paso a paso:
Número total de preguntas = 100%
Número de preguntas correctas = 27
Porcentaje de aciertos = 90%
Por eso,
Si 90% = 27
Luego ; 100% = x
Multiplicar en cruz:
0,9 veces = 27
x = 27 / 0,9
x = 30
Número de preguntas = 30
Answer:
given,triangle EFG is congruent to triangle HIJ,THEIR corresponding sides are equal,
so, 10x=x+45
10x_x=45
or,9x=45
therefore , x=5
again,
3y = y+14
or, 3y_y=14
or, y=14/2
therefore the value of y is 7.
so the value of x is 5 and y is 7.
hope its helpful to uh...
Answer:

Step-by-step explanation:
We need to find the value of
.
C stands for combination.
The formula of combination is as follows :

Here,
n = 19 and r = 1
So,

So, the value of
is 19.
Answer:
-4
Step-by-step explanation:
(4-2)³ = 8
so 8 - 3 x 4
is equal to -4
