Write a quadratic equation whose roots are -4 and one and who's leading coefficient is five

Alex

Step-by-step explanation:

- 4 and 1 are roots.

Therefore, (x + 4) & (x - 1) are factors and 5 is leading coefficient.

Therefore, required quadratic equation is:

$5 (x + 4) (x - 1) \\ = 5( {x}^{2} - x + 4x - 4) \\ = 5( {x}^{2} + 3x - 4) \\ = 5 {x}^{2} + 15x - 20$

Could someone please answer these two

exis [7]

Answer:

SEE BELOW

Step-by-step explanation:

1. find value of m

a^2 + b^2 = c^2

7.5^2+10^2=c^2

15+100=c^2

115=c^2

square it

=10.7 (not answer)

a^2+b^2=c^2

10.7^2+30^2=c^2

114.49+900=c^2

1014.49=c^2

square it

m=31.9

2.20^2 + 21^2 = 841

29^2=841

yes the triangle is right angled !!!

hope this helps :)
