Make quadratic equation with :-5 and -4

Mathematics
2 answers:
devlian [24]3 years ago

Answer:

x² + 9x + 20 = 0

Step-by-step explanation:

Given a solution x = - a for a quadratic equation then (x + a) is a factor

Here x = - 5 and x = - 4 , then corresponding factors are

(x + 5) and (x + 4)

The quadratic equation is then the product of its factors, that is

(x + 5)(x + 4) = 0 ← expand using FOIL

x² + 9x + 20 = 0

What’s the ara of each figure?
Grace [21]

Answer:

433 in.²

Step-by-step explanation:

Divide the figure into 2 rectangles

Area of the figure = area of the bigger rectangle + area of smaller rectangle

✔️Area of bigger rectangle = L*W

L = 29 in.

W = 13 in.

Area of the bigger rectangle = 29*13

= 377 in.²

✔️Area of the smaller rectangle = L*W

L = 7 in.

W = 8 in.

Area of the bigger rectangle = 7*8

= 56 in.²

✅Area of the figure = 377 + 56 = 433 in.²
