Answer:
29.4%
Step-by-step explanation:
the whole cirlce is 360 degrees which means 100%
to find the percentage of the shaded area, multiply the degrees by 100
⇒ 10.6 x 100 = 10600
then take the product and divide by 360
⇒ 1060 ÷ 360
⇒ 29.44
round to the nearet tenth of a percent
⇒ 29.4
Factor 16x^2 + 68x +42
16x^2 + 68x + 48
= 2(4x + 3)(2x + 7)
answer = 2(4x +3)(2x + 7)
