Evaluate The Expression When A = 7., 6 + A, A - 4, 4a

Evaluate the expression when a = 7.
6 + a
a - 4
4a

  Substitute 7 to a

6+a= 6+ 7= 13

a-4= 7-4= 3

4a= 4(7)= 28

First 25 term of arithmetic sequence 4,9,14,19,24   Answer: 4, 9, 14, 19, 24, 29, 34, 39, 44, 49, 54, 59, 64, 69, 74, 79, 84, 89, 94, 99, 104, 109, 114, 119, 124 Step-by-step explanation: The interval of each number is 5. Therefore, you just need to add 5 starting from 4. You can also see an obvious pattern that ends with 4 and 9, so you can use a shortcut method by following the pattern.

A Triangle Has Sides With Lengths 8x+6 And 5x-5. Find The Missing Side Length If The Triangle Has A Perimeter Of 7x+13.

a triangle has sides with lengths 8x+6 and 5x-5. find the missing side length if the triangle has a perimeter of 7x+13.   Answer: The third side is - 6x + 12. Step-by-step explanation: Perimeter of a triangle = Side₁ + Side₂ + Side₃ Side₃: y Given: Perimeter: 7x + 13 Side₁: 8x + 6 Side₂: 5x - 5 Side₃: y Equation: 7x + 13 = (8x + 6) + (5x - 5) + y 7x + 13 = (13x + 1) + y y = 7x + 13 - (13x + 1) y = 7x + 13 - 13x - 1 y = -6x + 12 The third side is - 6x + 12. Check: Perimeter = Side₁ + Side₂ + Side₃ 7x + 13 = (8x + 6) + (5x-5) + (-6x + 12) 7x + 13 = 8x + 6 + 5x - 5 - 6x + 12 7x + 13 = 7x + 13  (True)
