Answer:
AB = 10.06 cm
Step-by-step explanation:
Consider the given figure,
We have to find the length of side AB.
Lets rename the figure first, ABCD forms a rectangle. So , CB = DA = 12 cm
Also, EA = ED +DA ⇒ 15 = ED + 12 ⇒ ED = 15 - 12 ⇒ ED = 3 cm
Pythagoras theorem states that in a right triangle the sum of square of base and perpendicular is equal to square of hypotenuse.
Using, Pythagoras Theorem on Δ EDC,

ED = 3 cm , EC = 10.5, Substitute, we get,

Solve for DC, we get,





Since, ABCD is a rectangle. Thus, DC = AB
Hence, AB = 10.06 cm
Answer:
|-4|, |-4 1/4|, 4 1/2, 4 3/4
Step-by-step explanation:
The absolute value lines, | |, make the value inside of them positive. For example, the absolute value of -2 is 2. In this example, although -4 and -4 1/4 become positive, they are still lower than 4 1/2 and 4 3/4.

Answer:
32
Step-by-step explanation:
Substitute a = - 2 into the expression and evaluate
3(- 2)² - 7(- 2) + 6 = 3(4) + 14 + 6 = 12 + 14 + 6 = 32
Answer:
A
Step-by-step explanation:
Area = length times height times width
Area = 164 x 82 x 9.8
= 131790.4
Multiply by 7.48 since it takes 7.48 gallons to fill a cubic foot then you find the answer of A.
