Algebraic Expressions And Equations Class V1- Red

When we substitute x = 6 into the expression 7x + 4, we get 7(6) + 4 = 42 + 4 = 46. Therefore, the correct answer is 46.

The correct answer is 23 because when we substitute y=5 and z=6 into the expression y + 3z, we get 5 + 3(6) which simplifies to 5 + 18 = 23.

The given expression is 5(2d + 2e), which can be simplified by distributing the 5 to both terms inside the parentheses. This results in 10d + 10e, which is the same as the correct answer.

The given expression is 9x + 24y. The correct answer, 3(3x+8y), is obtained by factoring out the greatest common factor (GCF) from the terms 9x and 24y. The GCF of 9x and 24y is 3, so we divide both terms by 3 to get 3x and 8y. Therefore, the expression can be simplified as 3(3x+8y), which is the correct answer.

The given expression is a combination of like terms. By combining the terms with 'a' and 'b', we can simplify the expression to a + 4b.

The expression "Product of 9 and a number r" can be written as 9r. This is because when we multiply 9 by any number r, we get the product 9r. Therefore, the correct answer is 9r.

The expression "d + 6" represents Bob's age in 6 years time. Adding 6 to his current age (d) gives us the age he will be after 6 years.

The expression "p-14" represents the phrase "14 decreased from a number p". This means that we are subtracting 14 from the number p.

The expression p² + p² + p² can be simplified by combining like terms. Since all three terms have the same base (p) and exponent (2), we can add the coefficients together to get 3p². Therefore, the correct answer is 3p².

The given expression (2^3)^4 can be simplified by raising 2 to the power of 3, which equals 8. Then, 8 is raised to the power of 4, resulting in 8^4 = 2^12 = 4096. Therefore, the correct answer is 212.
