Answer:
30 cm²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the height )
Here b = 6 and h = 10 , thus
A = × 6 × 10 = 3 × 10 = 30 cm²
and 7² = 7 × 7 = 49
Answer:
Yes.
Step-by-step explanation:
They are both divisible by 21.
Answer:
49.6 is what y is equal to
Step-by-step explanation
Answer:
first method
subtract 5 from both side
2x + 5 -5 = 12 - 5
:. 2x = 7
:. X= 2
7
divide 2 from both side
X= 2x 7
2 2
:. X= 3.5
second method
2x = 12 - 5
2x = 7
X= 2 ÷ 7
:. X= 3.5
Answer: 1, 2, 4, or 5
Step-by-step explanation:
The relationship in #3 is a function because all the x values are distinct, that is, none are repeated. (Y values don't matter.)
A function will not repeat any x values so if your goal is for the relationship in #4 to NOT be a function, repeat one of the x values. Any one will work.
