Answer:
<u>It</u><u> </u><u>is</u><u> </u><u>3</u> <u>6</u> <u> </u> <u>cm</u>
Step-by-step explanation:
In equilateral triangle, all sides are equal.
but side = 12 cm
Answer: Perimeter = 36 cm
Concept:
Here, we need to know how to find the perimeter of an equilateral triangle.
An equilateral triangle is a triangle in which all three sides have the same length.
Perimeter (equilateral triangle) = 3s
s = side length
Solve:
<u>Given information</u>
Side length = 12 cm
<u>Given expression</u>
Perimeter = 3s
<u>Substitute values into the expression</u>
Perimeter = 3 (12)
<u>Simplify by multiplication</u>
Perimeter=

Each increases by a certain amount called the common difference 4.4-2.8=1.6 6-4.4=1.6 7.7-6=1.7 hmm, some error maybe you meant 7.6 common difference is 1.6 answer is C
Answer:
b = 104
Step-by-step explanation:
Slope is expressed as;
m = y2-y1/x2-x1
14 = b - 6/5-(-2)
14 = b - 6/5+2
14 = b-6/7
Cross multiply
b-6 = 14 * 7
b - 6 = 98
b = 98 + 6
b = 104
Answer:
Step-by-step explanation:
Substituting x and y values into the equations, we can get the equation
y = 7 -3x
slope: -3
