For a square, diagonal d=ℓ2d=\ell\sqrt{2}. Side length ℓ=d/2=12/2=62\ell=d/\sqrt{2}=12/\sqrt{2}=6\sqrt{2}. Area = ℓ2=(62)2=72\ell^2=(6\sqrt{2})^2=72. Correct answer: A. CLI geometry tests recognition of diagonal-side relations in squares, a common shortcut versus repeated Pythagoras.

Perimeter = 3×side=3×11=333 \times \text{side} = 3 \times 11 = 33. Correct answer: B. Placement exams in geometry often include equilateral triangles to confirm recognition of special polygons and formula fluency.

Distance = speed × time = 50×2.5=12550 \times 2.5 = 125. Correct answer: D. CLI reasoning ensures students apply rate formulas correctly. Time-speed-distance problems check understanding of proportional reasoning, vital for both mathematics and real-world problem contexts like navigation and planning.

Volume formula: V=πr2h=π(9)(10)=90πV = \pi r^2 h = \pi (9)(10) = 90\pi. Correct answer: C. CLI placement geometry covers solids like cylinders to ensure readiness for applied math in science and engineering.

For ∣A∣>k|A|>k with k>0k>0, split into two strict inequalities: A>kA>k or A<−kA<-k. Here A=3x+2A=3x+2 and k=11k=11. Case 1: 3x+2>11⇒3x>9⇒x>33x+2>11\Rightarrow 3x>9\Rightarrow x>3. Case 2: 3x+2<−11⇒3x<−13⇒x<−1333x+2<-11\Rightarrow 3x<-13\Rightarrow x<-\tfrac{13}{3}. Combine with “or”: x<−133x<-\tfrac{13}{3} or x>3x>3. This matches A. CLI Algebra emphasizes translating absolute value inequalities into compound inequalities and retaining strict vs. non-strict symbols. A number-line visualization helps: ∣3x+2∣>11|3x+2|>11 means the expression 3x+23x+2 lies more than 11 units from 0, producing two rays extending away from the center—hence the union of intervals. A quick test confirms boundaries are not included (strict “>”): plugging x=3x=3 gives ∣11∣=11|11|=11 (not greater), so it’s excluded; x=4x=4 gives ∣14∣=14>11|14|=14>11 (included), and x=−5x=-5 gives ∣−13∣=13>11|-13|=13>11 (included). Mastery of these transformations prepares students for more advanced topics like piecewise functions and optimization with constraints, both common in placement settings.
