i would have to fight over B or C bc those are really good answers
Answer:
A=10 cm
B=5 cm
Area of square = 25 cm
Step-by-step explanation:
Since that is an equilateral triangle based off the fact that all the sides are the same variable (a) then that means 30 divided by 3 which equals 10. So now we know that a = 10. Lets input that information for the rectangle. Since there are 2 a's that equals 20 and the perimeter is 30 so b has to be 5 since 5 times 2 is 10 plus 20 equals 30. so now we know that a=10 and b=5 so our squares sides are all 5. The area of the square is 25
Answer:
1,456
Step-by-step explanation:
The sum of n terms of a geometric sequence with first term a1 and common ratio r is given by ...
Sn = a1·(r^n -1)/(r -1)
For your series with a1=4, r=3, and n=6, the sum is ...
S6 = 4·(3^6 -1)/(3 -1) = 2·728 = 1,456

Answer:
y = 3/4x + 2
Step-by-step explanation:
If we take the given points to be (0, 2) and (4, 5), then the slope is ...
m = (y2 -y1)/(x2 -x1) = (5 -2)/(4 -0) = 3/4
The y-intercept is given by the point (0, 2). So, the equation is ...
y = mx + b . . . . . . line of slope m with y-intercept b
y = 3/4x + 2
