Answer:
26 inches
Step-by-step explanation:
Height of the triangular plane (h) = 36 inch
Area of the triangular plane = 468 inch²
Let the length be l inch
Step 1: It tells you that x = 4, so replace x with 4 in the equation. 4 + 3y = 16
Step 2: Use the substitution method to subtract 4 from both sides. (4-4) + 3y = (16 - 4) ——> 3y = 12
Step 3: You must now get the variable y alone, so divide 3 to both sides. 3y/3 = 12/3 ——> y = 4
The answer is (4,4)
Answer:
2
Step-by-step explanation:
-10 + x = - 8 add 10 to both sides of the equation
x = 2
