What is the missing operations to 4×9+7×9=(4+7)×

9, if you're asking for only the number of it. But If it needs more then please elaborate.

Step-by-step explanation:

4×9+7×9=(4+7)×9

36+63=11*9

99=99

Order Of Operation Helps!

4×9+7×9=(4+7)× 9

Step-by-step explanation:

4×9+7×9=(4+7)×?

Distributive property is used on the left hand side

Distributive property says

a(b+c) = a*b + a*c

or we can say a*b + a*c = a(b+c)

'a' is common for b  and c

So we multiply 'a' with (b+c)

Apply distributive property for the given equation

4×9+7×9=(4+7)×?

9 is in common . 9 is distributed with 4  and 7.

So , the missing operation is multiply by 9

4×9+7×9=(4+7)× 9

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
