Ask yourself f(x) equals X +18 to the second power +12
Answer:
4
−
4
+
8
2
+
8
Step-by-step explanation:
Answer:
because the length is 4 feet more than the width
=> the length is x + 4 (feet)
because the base has an area of 21 square feet
=> x(x + 4) = 21
<=> x² + 4x = 21
Answer:
x = 11
y = 3
Step-by-step explanation:
In a parallelogram opposite sides are equal.
8x = 88
x = 88/8
x = 11
4y - 7 = y + 2
4y = y + 2 + 7
4y = y + 9
4y - y = 9
3y = 9
y = 9/3
y = 3
Answer:
2(x+3)=2x+6
2x+6=2x+6
Step-by-step explanation:
2(x+3)=2x+6
2x+6=2x+6
