Solve the quadratic equation by factoring 9x2+24+20=4

Mathematics

AnnyKZ [126]3 years ago
5 0

Answer:

Final answer is x=-\frac{4}{3} and x=-\frac{4}{3}.

Step-by-step explanation:

Given equation is 9x^2+24x+20=4.

Now we need to solve that by factoring.

9x^2+24x+20=4

9x^2+24x+20-4=0

9x^2+24x+16=0

9x^2+12x+12x+16=0

3x(3x+4)+4(3x+4)=0

(3x+4)(3x+4)=0

(3x+4)=0, (3x+4)=0

3x+4=0, 3x+4=0

3x=-4, 3x=-4

x=-\frac{4}{3}, x=-\frac{4}{3}

Hence final answer is x=-\frac{4}{3} and x=-\frac{4}{3}.

A drawing of a surfboard in a catalog, it shows its length as 8 4/9 inches. Find the actual length of the surfboard if 1/3 inch
Bond [772]

Answer:

9.5 feets

Step-by-step explanation:

Length of drawing = 8 4/9 inches

Scale : 1/3 inch in drawing = 3/8 actual length

Length of drawing / drawing scale

8 4/9 = 76/9 inches

Number of 1/3 inches in total length of drawing :

76/9 ÷ 1/3

76/9 * 3 / 1

(76*3) /(9*1) = 228 /9 = 9 3/9 = 9 1/3

9 1/3 * 3/8 foot

(228 / 9) * (3 /8)

(228/3) * (1/ 8)

228 / 24

= 9.5 feet
