Answer:
A.Area of the base
Step-by-step explanation:
these is obtained by multiplying the length and width of the base to get the area of the base
1. Subtract 15 to the other side (5x^2 = 36)
2.Square root both sides to remove the squared of 5x^2 (sqrt(5x^2) = sqrt(36) simplified to 5x = 6)
3. divide by 5 to get x = 6/5
Final result is 6/5
Answer:
Step-by-step explanation:
1)
y = 5x-4 when x=5
y = 5*5-4
y = 25-4
y = 21
y = -2/5x + 3/8 when x = 1/3
y = -2/5 * 1/3 + 3/8
y = -2/15 + 3/8
y = -6/120
y = -1/20
y = 3x + 12 when x = 4
y = 3*4 + 12
y = 12 + 12
y = 24
