Answer:

D

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0, then the discriminant is

Δ = b² - 4ac

x² + 3x - 4 = 0 ← is in standard form

with a = 1, b = 3, c = - 4

b² - 4ac = 3² - (4 × 1 × - 4) = 9 - (- 16) = 9 + 16 = 25 → D

Which of the following equations describe the line shown below? <br><br>Check all that apply.
WITCHER [35]
Here, first we need to calculate the slope of the line, 
Here, Coordinates = (-6, 2) (-1, -4)
m = y2 - y1 / x2-x1
m = 2 + 4 / -6 + 1
m = 6/-5
m = -6/5

Now, Take first coordinate: y - 2 = -6/5 (x + 6)
Second coordinate: y + 4 = -6/5 (x + 1)

In short, Your Answers would be Option C & D

Hope this helps!

I’ll give brainliest who ever has the right answer
Leni [432]

Answer:

32m

Step-by-step explanation:

because we know that 3cm = 4 m, we can replace the top length with 4m, we also know that 6cm must equal 8m because of 3cm ×2 = 6cm so 4m ×2 = 8m. now we know 2of the sides so the area is just 4m ×8m because area = length times width. 4m × 8m = 32m
