We can use the cosine rule to find the third side:
c² = a² + b² -2abcos(C)
c = √(42² + 35² - 2(42)(35)cos(120)
c = 66.78
The answer is D.
Answer:
x=2
Step-by-step explanation:
5x=3x+4
5x-3x=4
2x=4
x=4/2
x=2
All the best for ur exams .........Mine are going on too btw.......
The distributive property "distributes" a number through all numbers/terms in a set of parentheses by multiplication.
EXAMPLES
Equivalent expressions are the first and last steps. The middle step just shows the work.
5(2 + 3x)= (5*2) + (5*3x)= 7 + 15x
4(2x + 4y)= (4*2x) + (4*4y)= 8x + 16y
10(4x + 5)= (10*4x) + (10*5)= 40x + 50
ANSWER:
Only one pair below is needed for your answer.
5(2 + 3x)= 7 + 15x
4(2x + 4y)= 8x + 16y
10(4x + 5)= 40x + 50
Hope this helps! :)
The formula for finding circumference is C=2*pi*r. So C is the circumference that you are trying to find. Pi is 3.14. And r is the radius. Now, it does not tell you directly what the radius is, but the diameter of a circle is basically how far across is it. So in this case, 14. The radius of a circle is half of it's diameter, so half of 14 is 7. So, multiply 2*3.14*7, to get the circumference. You get 43.96.
Answer:
Neither
Step-by-step explanation:
Although the lines intersect it is not at a 90° angle meaning it's neither perpendicular or parallel.
