Name Key Date Black Algebra 1: Verbal Expressions, Order of Operations and Properties Test Review SOLA11 1 Kristina, the oldest member of the cheer squad at Nansemond River High School, is 8 years less than one-half the age of the coach. If the coach is x years old, write an expression that describes Kristina's age. x-8 2 Which statement correctly represents x + √9 ? SOL ALS a. The number x increased by the square root of 9 x+√9 b. The number x plus the cube root of 9x + C The sum of x and 9 cubed X + 93 d. The number x decreased by the square root of 9 x - √9 3 The height of a triangle is 7 units less than b, its base. Write an expression to represent the area of the triangle (Formula: A = blt) height(h) = b-7 A=b(6-7) SOL ALI 4 Write an expression that correctly describes "the quotient of a number cubed and 4"? n³ 4 hdach verbal expression to the c expression to the correct algebrale expres from Bach box undernea SOLALI 4x-5 B E 5 siting the 5-4x AUDF A The difference of five and four times x D5-4x Five minus four times x B The product of 4 and x decreased by 5 E4x-5 Five less than four times x C Five decreased by four times x 5-4x FFive minus the product of four and x 6. Write a verbal expression for the algebraic expression 2(x + y). SOL: 2 times the sum of x and y 7. Write an algebraic expression for "2 times the sum of x cubed and 3". SOL: 2(x³ + 3) 8. What is the value of the expression 2x - 3y when x = 5 and y = -2? SOL: 2(5) - 3(-2) = 10 + 6 = 16 9. What is the value of the expression 2m + m² when m = 2? SOL: 2(2) + 2² = 4 + 4 = 8 10. What is the value of the expression (x²y - 2x) / |x - y| when x = 6, y = 4, and z = 2? SOL: (6² * 4 - 2 * 6) / |6 - 4| = (36 * 4 - 12) / |2| = (144 - 12) / 2 = 132 / 2 = 70 11. What is the value of the expression √(ab² + 4b - 6) when a = 2 and b = 5? SOL: √(2 * 5² + 4 * 5 - 6) = √(50 + 20 - 6) = √70 - 4 Math #4: 12. Evaluate the expression |6(c - a) + 5(a + c)| when a = -8 and c = 10. SOL: |6(10 - (-8)) + 5(-8 + 10)| = |6(18) + 5(2)| = |108 + 10| = 118 13. What is the value of the expression 2(x + 3) - 4y, if x = 4 and y = -2? SOL: 2(4 + 3) - 4(-2) = 14 + 8 = 22 14. What is the value of √(x² - 7) / 6 when x = 4? SOL: √(4² - 7) / 6 = √(16 - 7) / 6 = √9 / 6 = 3 / 6 = 1/2
