4 0

Hello here is a solution :
x² − 8x − 4 = 0.
quadratic equation ax²+bx+c = 0 when : a=1 and b= -8 and c = -4
discriminant : d = b²-4ac d= (-8)²-4(1)(-4) =64+16 =70
x= (-b-rot(d))/2a x'= (-b+rot(d))/2a .......conrinu

Square A is a scaled version of square B. The dimensions of square A are three times the dimensions of square B. The area of squ

denis23 [38]

Answer:

The side of square A is 30 cm.

Step-by-step explanation:

Given that,

The dimensions of square A are three times the dimensions of square B.

The area of square A is 900 sq cm.

Side of square A = 3( side of square B)

Let the side of square B is b. So,

Side of square A, a = 3b

We know that, the area of square is side². So,

$(3b)^2=900\\\\9b^2=900\\\\b^2=100\\\\b=10\ cm$

Side of square A, a = 3(10) = 30 cm

Hence, the side of square A is 30 cm.

hram777 [196]

I also worked it out but I got -5/3

2(6p-5) ≥ 3(p-8) -1

12p-10 ≥ 3p-24-1

12p-10 ≥ 3p-25

12p-3p ≥ -25+10

9p ≥ -15

-15/9

P ≥ -5/3
