Will give brainliest and 40 points. the coordinates of the vertices of △def are d(−4, 1) , e(3, −1) , and f(−1, −4) . which statement correctly describes whether △def is a right triangle? a. △def is a right triangle because df is perpendicular to ef . b. △def is a right triangle because de is perpendicular to ef . c. △def is a right triangle because de is perpendicular to df . d. △def is not a right triangle because no two sides are perpendicular.

Let f(x) = x+3 and g(x) = 1/x the graph of (fog)(x) is shown below what is the range of (fog)(x)?

For each polynomial, determine the degree and write the polynomial in descending order. a. –4x^2 – 12 + 11x^4 b. 2x^5 + 14 – 3x^4 + 7x + 3x^3

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.
