7 multiplicado por 49 =343
a) To find the missing side length on triangle A, we can use the Pythagorean theorem.
a^2 + 12^2 = 13^2
a^2 + 144 = 169
a^2 = 25
a = 5 cm
5 and 12 = 5 and 12
b) The two triangles are congruent because they have two side lengths in common. If at least two side lengths are the same on two triangles, then they are congruent. In addition, these triangles have one angle in common as well.
Hope this helps!! :)
Answer:
6. r=2
8.x=3
Step-by-step explanation:
6. 4r-3=5
4r-3=5 add 3 to both sides
4r=8 divide 4 by both sides
r=2
8. 5x-6=9
5x-6=9 add 6 to both sides
5x=15 divide 5 by both sides
x=3
Answer:
C
Step-by-step explanation:
When we talk of domain, we are referring to the values we have on the x axis
By considering the range of values we have on the x-axis, we have the domain we want
We have the gymnast complete the sessions in 95 seconds.
This means that the highest point on the x-axis is 95 seconds
But how do we measure time? we do this in form of integers
So the correct domain will be all
integers between 0 and 95
which can be represented as 0≤x≤95
