The answer is choice D because the expression 6x^3+x^2-3 is the same as 6x^3+1x^2+0x+(-3). Notice the coefficients are 6, 1, 0, -3
The expression x-7 is in the form x-k where k = 7. This is the test root which is placed outside of the synthetic division bar as shown in choice D.
ANSWER:
We know that angle fromed by same arc are congruent. so
∠ACB ~ ∠ADB
∠CAD ~ ∠CBD
Therefore, ΔCAF ~ ΔDBF by AA similarity. So, By CPCT
arcAC = arcBD.
Since the end of the slide is 1 foot above the ground, the vertical rise of the
<span>slide is 8 - 1 = 7 feet, and since the slide rises at a 45 degree angle it will </span>
<span>have a horizontal run of 7 feet as well. Thus by Pythagoras the length of the </span>
<span>slide is sqrt(7^2 + 7^2) = sqrt(98) = 9.90 feet, which is about 10 feet.</span>
