It is called evaluating expression. In order to find the value of an algebraic expression you need to substitute a number for each variable and perform the arithmetic operations and the letters can stand for the numbers and it is called evaluating the expression.
Answer:
- Yes its an isosceles triangle but not a right angle triangle.
part A:
Two sides are equal in the triangle of 5. Its an isosceles triangle.
part B:
if right angle triangle, then use the formula:
short side² + short side² = long side²
( 5√2 )² + 5² = ( 5√2 )²
75 = 50
Therefore, its not a right angle triangle.
Nickels are 5 cents, and dimes are 10 cents.
(By luck..) eventually you can have 12 dimes, meaning you have 120 cents, or $1.20 ... 20-12=8.. meaning you used 12 dimes and are missing 8 more coins. which means you can have 8 nickels which is 40 cents. 120+40=160 cents or $1.60
Hope this helped.
Answer:
C
Step-by-step explanation:
All the other answers are the same worded differently except c.
The distance between 6 and -6 is 12 so that is not correct for the absolute value of -6
Answer:
The answer is D.
Step-by-step explanation:
Using Pythogaras' Theorem to find the value of x. The formula is, hypo.² = side² + side² :
side = 8 units
side = 12 ÷ 2
= 6 units
hypo.² = 8² + 6²
= 100
hypo. = √100
= 10
