Hey!
take the group of numbers and put them from least to greatest. then, take the lowest number and subract that from the highest number.
for example, if i have the numbers 2,7,4,5
i would put them in order (least to greatest), which would be: 2,4,5,7
then, you subract 7-2, and that equals 5 :)
hope this helped!! have a great day / night!
Answer:
Step-by-step explanation:
<1=180°-74° so <1=126°
<2=180°-90° so <2=90°
<3=180°-116° so <3=64°
<4=180°-65° so <4=115°
by using ° =(3)180°/5 -<1 -<2 -<3 -<4 =<5
you find out the last.
Answer:
1. x = ±9
2.
3. 12 and -12.
4. Antoine is incorrect. There exists two solutions x=5 and x= -5.
Step-by-step explanation:
We have,
Question 1. i.e. i.e. x = ±9.
Question 2. i.e. i.e. i.e.
Question 3. [tex]f(x)=x^{2}-144[tex]
For the roots, we take, [tex]x^{2}-144=0[tex] i.e. [tex]x^{2}=144[tex] i.e. x = ±12.
So, the options are 12 and -12.
Question 4. We have [tex]f(x)=x^{2}+25[tex]
For the roots, we take, [tex]x^{2}+25=0[tex] i.e. [tex]x^{2}=25[tex] i.e. x = ±5.
So, Antoine is incorrect. There exists two solutions x=5 and x= -5.
Answer:
x = 12
Step-by-step explanation:
they are virtical menaing they are the same value
6x + 7 = 8x - 17
6x + 24 = 8x
24 = 2x
12 = x
