Answer:

<h2>x = -4 ± 2√(3)  </h2><h2 />

Step-by-step explanation:

Discriminant Δ = √(8²-4×(1)×(4)) = √(48) = √(4×12) = √(4)×√(12) = 2√(12)

then x = (-8 ± 2√(12))÷2 = -4 ±√(12) = -4 ±√(3×4) = -4 ± 2√(3)

Please solve for me. C=1/2x(a+w)
Gnoma [55]

Answer:

C= 1/(2ax+2aw)

Step-by-step explanation:

C=1/2x(a+w)

Multiply a and w by 2x. Take note of the sign.

C= 1/(2ax+2aw)

when writing your answer, you don't need the brakets. I just put them so you'd understand that all those characters in the bracket are the denominator.

Please rate 5 stars, thanks, give brainliest. Thanks.

ΔABC is similar to ΔMNO. The scale factor from ΔMNO to ΔABC is 3∕2 . If the area of ΔMNO is 10 square units, what's the area of
Andrews [41]

Answer:

The area of ΔABC= 6.667 square units

Step-by-step explanation:

ΔABC is similar to ΔMNO.

The scale factor from ΔMNO to ΔABC is 3∕2

the area of ΔMNO is 10 square units,

The area of ΔABC/the area of ΔMNO

= 2/3

The area of ΔABC/10= 2/3

The area of ΔABC= 2/3 * 10

The area of ΔABC= 20/3

The area of ΔABC= 6 2/3

The area of ΔABC= 6.667 square units
