Answer:

I believe it's A=5 times 9 but since the triangle is special (3-4-5), it could be 12 times 5. Hope this kinda help :)

PLS HELP ME IM BEING TIMED AND I HAVE 20 MINS TO TURN IN.
Natasha_Volkova [10]

Answer:

2.a)  3 ( x - 1 ) = 5x - 6 (Because the sides of a square are always equal)

b) 3 ( x - 1 ) = 5x - 6

    => 3x - 3 = 5x - 6

    => 3x - 5x = -6 + 3 (Law of transposition)

    => -2x = -3

    => -x = -3/2

    => -x = -1.5

    => x = 1.5 (By cancelling out the negative sign from both the sides)

c)  3(x-1) = 3 (1.5 - 1)

    => 3 (0.5)

    => 3 * 0.5 = 1.5

Both the angles are 1.5 because they are equal

If my answer helped, please mark me as the brainliest!!

Thank You!

Without solving determine the number of real solutions for each quadratic equation
snow_lady [41]

Step-by-step explanation:

b^2-4b+3=0

b²-3x-b+3=0

b(b-3)-1(b-3)=0

(b-3)(b-1)=0

either

b=3 or b=1

.

2n^2 + 7 = -4n + 5

2n²+4n+7-5=0

2n²+4n+2=0

2(n²+2n+1)=0

(n+1)²=0/2

:.n=-1

.

x - 3x^2 = 5+ 2x - x^2

0=5+ 2x - x^2-x +3x^2

0=5+x+2x²

2x²+x+5=0

comparing above equation with ax²+bx +c we get

a=2

b=1

c=5

x={-b±√(b²-4ac)}/2a ={-1±√(1²-4×2×5)}/2×1

={-1±√-39}/2
