Answer:
x= −1/2, x=52/5
Step-by-step explanation:
2(x+7)=13
(2)(x)+(2)(7)=13(Distribute)
2x+14−14=13−14
2x=−1
2x/<u><em>2</em></u>=−1/<u>2</u>
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
5(x−7)=17
(5)(x)+(5)(−7)=17(Distribute)
5x+−35=17
5x−35=17
5x−35+35=17+35
5x=52
5x/<u><em>5</em></u>=52/<u>5</u>
1. you can use fractions, reduce the number, or compare them and if they are the same
then they are classified as proportional.
2. you can use a graph by graphing two sets of numbers, if it’s proportional it will form a straight line that goes through the origin.
Answer:
d
Step-by-step explanation:
We just need to use the formula:
c = 3.14(r)²
So we can insert the radius here
c = 3.14(7)²
c = 3.14(49)
c = 153.86
So your answer is d.
90, 45, 45
a right triangle has an angle 90 degree, and the three angles of a triangle make a sum of 180,
so the other two angles make up the other 90 degree
the right triangle is isosceles, so the other two angles are congruent, of the same degree. Each of them is 45 degree
