Answer: -3
Step-by-step explanation:
-3x+ 7x+ 35= 5x + 38
You solve the distributive property on the left side and set it equal to the right
4x+35= 5x+38
-4x -4x
35= x+38
-38 -38
X=-3
Answer:
slope = 4/2
simplified = 2
Step-by-step explanation:
use rise over run to find slope
Answer:
38
Step-by-step explanation:
The sum of the measures of the 4 angles is 180°.
m<A + m<B + m<C + m<D = 180
60 + 2x + 3x + 25 = 180
5x + 85 = 180
5x = 95
x = 19
m<B = 2x = 2(19) = 38

Answer:
I, III
Step-by-step explanation:
You know from your study of the Pythagorean theorem that a triangle with sides 3, 4, and 5 will be a right triangle. Any scaled version of this triangle will also be a right triangle, so it is helpful to learn to recognize when scaled values of these numbers are used.
I -- the scale factor for a 3-4-5 right triangle is 2/10
II -- no isosceles right triangle has integer side lengths. (not a right triangle)
III -- the scale factor for a 3-4-5 right triangle is 1/13
IV -- the lengths do not form a triangle
Triangles I and III are right triangles.
_____
<em>Additional comment</em>
The sides of an isosceles right triangle have the ratios 1 : 1 : √2. The square root of 2 is irrational. No scaled version of this triangle can have rational side lengths.
