On a piece of paper, use a protractor and a ruler to construct two equilateral triangles: one with a side length of 4 in. and one with a side length of 5 in.

which statement is true about the two triangles?

a. the two triangles are the same size and same shape.

b. the two triangles are the same shape but not the same size.

c. it is impossible to construct equilateral triangles with these side lengths.

d. the two triangles are the same size but not the same shape.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

What is the absolute value of the complex number -4-sqrt2i

Gabriel determined that his total cost would be represented by 2.5x + 2y – 2. his sister states that the expression should be x + x + 0.5x + y + y – 2. who is correct? explain.
