Answer:
a ≤ 2
Step-by-step explanation:
Simplify both sides of the inequality
42a + 48 ≤ 132
Subtract 48 from both sides
42a + 48 − 48 ≤ 132 − 48
42a ≤ 84
Divide both sides by 42
42a/42 ≤ 84/42
a ≤ 2
Answer:
441
Step-by-step explanation:
x^2 + 42x + c
Take the coefficient of x
42
Divide by 2
42/2 = 21
Square it
21^2 =441
This is the value of c
First is to get the given data that we might be able to use for computation.
H = 8 inches
Area = 96
B1 = B1
B2 = B1+6
Next is to know the area of a trapezoid
Area = H x (B1 + B2)/2
96 = 8 x (B1 + B1 + 6) / 2
96 = 8 x (2B1 + 6) /2
96 = 4 x (2B1 + 6)
14 = 2B1 + 6
2B1 = 8
B1 = 4
B2 = 10
Answer:
61
Step-by-step explanation:
DCB = 180-ACD = 180-58 = 122
ECB = DCB/2 = 122/2 = 61
