Answer:
18 is the answer
Step-by-step explanation:
We know this because The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54
Answer:
The answer is 5X+16
Step-by-step explanation:
The formula for perimeter of a triangle is a+b+c.
meaning we are adding up everything.
That is
(x)+(x+11)+(3x+5).
collect like terms.
and u end up getting
5x+16
Reflection:
Reflection is a type of rigid transformation which requires the turning of an object, shape or figure about a reference point or line. Therefore, the needed additional information is ∠DFE ≅ ∠ DFG.
Reflection implies turning the given triangle DEF about its side DF, so as to produce an image with the same dimensions but different orientation.
The required proof by Side-Angle-Side (SAS) implies that the relations will be in respect of two of its sides and their included angle.
So According to the above statement,
GF ≅ FE (: given)
DF is the common side to triangles DEF and DFG.
DFG is the included side.
Thus ∠DFE ≅ ∠ DFG (Side-Angle-Side postulate, SAS)

Answer:
9:5 = 1428:x
ratios can also be written as fractions, so
9/5 = 1428/x
solve for x
9/5 × x = 1428
x = 1428 / (9/5)
x = 918
