First take lcm and see your answer
Hi
The answer is <em>D. 39 degrees. </em>The area where b is shows an acute angle. The only answer shown with an acute angle is 39. 141 and 180 are obtuse angles, and 90 is a right angle.
The transformations that always produce congruent figures are TRANSLATIONS, REFLECTIONS, and ROTATIONS. These transformations are isometric, thus, the figures produced are always congruent to the original figures.
The transformation that sometimes produce congruent figures is dilation. It can be enlargement or contraction.
rule: (x,y) → (x+4,y+8)
X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7
We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25
answer: the number would be: -25.
