A number pattern would be something that just gets repeated over and over
so for this example 120+120+120=360
so the least common multiple is 120 because adding 120, three times will get you to 360
Answer:
B: x=-5 and x=4
Step-by-step explanation:
f(x)= x^2 + x -20
To find the zeros we replace f(x) with 0
now we solve for x
LEts factor x^2 + x -20
sum is +1 and product is -20
5 * (-4)= -20
5 + (-4) = +1
x^2 + 5x - 4x - 20 = 0
(x^2 + 5x)+(- 4x - 20) = 0
x(x+5) -4 (x+5) = 0
(x-4)(x+5)=0
Set each factor =0 and solve for x
x- 4 =0 so x=4
x+5 =0 so x=-5
x=-5 and x=4
Answer:
30
Step-by-step explanation:
use the Pythagorean theorem
You need to divide 71 / 10.
The statement that justifies why ∠EBC measures 90° is that the sum of the measures of two complementary angles is 90 degrees.
<h3>What are
complementary angles?</h3>
The complementary angles are angles that when we find their sum it will be equal to 90 degrees and that is why its been regarded as the complementary angles.
We can see that m∠ABD and m∠DBC are complementary, because m∠ABD + m∠DBC=90°
Therefore, The statement that justifies why ∠EBC measures 90° is that the sum of the measures of two complementary angles is 90 degrees.
