So, the ones that are on the inside of the shapes are angles, and the lines are sides. What you’ll do is, you’ll read them as: side angle side(SAS) or, side side side(SSS). So for example problem 3 would be side angle side(SAS), because there is one angle in the middle and two sides on the out side. If you read one as angle angle side(AAS) or side side angle(SSA) or angle side angle(ASA) you’ll put not congruent. I hope this helps.
X intercpe is when y=0
0=6x^2+10x-4
factor
0=2(3x^2+5x-2)
assume
0=3x^2+5x-2
0=(x+2)(3x-1)
set to zero
x+2=0
x=-2
3x-1=0
x=1/3
x intercepts are -2 and 1/3
D is answere
Answer:
Not enough information.
Step-by-step explanation:
Make sure you know the formula pertaining to the question.
1. c=2(pi)(r)
2. c=2(pi)(d)
r= radius
d= diameter
c= sircumference
So we are given that the circumference of a circle is 12.3pi and the radius is unknown.
So let's plug in the known values
**we use the formula with the radius, becuase we are looking for the radius.
c=2(pi)(r)
12.3(pi)=2(pi)(r)
divide each side by pi
12.3=2(r)
divide each side by 2
r=6.15 in.
List out all of the factors to 32.
1, 2, 4, 8, 16, 32
From the list, we either have 4 or 16 as our number.
Prime factorisation for 4 is 2 x 2 and prime factorisation for 16 is 2 x 2 x 2 x 2
Thus, that doesn't help our case.
Looking at our requirement: the sum of its digits is odd.
Well, 4 can be rewritten as 0 4 and its sum is even.
The sum for 1 + 6 is obviously odd, which means that 16 is the number.
