Ask google because I’m so dumb I can’t even read this ! Have a great day I hope you find your answer
Answer:
The answer to your question is below
Step-by-step explanation:
Formula
Triangle's Area = 1/2 bh/2
Trapezoid's area = 1/2 (b1 + b2)h
Parallelogram's area = bh
Rectangle's area = bh
Considering the formulas, we can conclude that:
a) The first choice is true, both formulas have 1/2 in.
b) The second choice is also true, both equations are the same
c) The third choice is incorrect
d) This choice is correct, the bases are added,
e) This choice is incorrect, the sides are not added.

Circumference = πD
------------------------------------------------------------------------
Given that the circumference is 75cm, find Diameter:
------------------------------------------------------------------------
πD = 75
D = 75 ÷ 3.14
D = 23,89 cm
------------------------------------
Find Radius:
------------------------------------
Radius = Diameter ÷ 2
Radius = 23.89 ÷ 2
Radius = 11.94 cm
------------------------------------
Find Surface Area:
------------------------------------
Area = πr²
Area = 3.14 x 11.94²
Area = 447.65 cm²
------------------------------------
Answer: 447.65cm²

Answer:
Step-by-step explanation:
12) A(x, 5) and B(-4,3)
slope = -1
We want to determine the value of x so that the line AB is parallel to another line whose slope is given as -1
Slope, m is expressed as change in y divided by change in x. This means
Slope = (y2 - y1)/(x2 - x1)
From the information given
y2= 3
y1 = 5
x2 = -4
x1 = x
Slope = (3-5) / (-4-x) = -2/-4-x
Recall, if two lines are parallel, it means that their slopes are equal. Since the slope of the parallel line is -1, therefore
-2/-4-x = -1
-2 = -1(-4-x)
-2 = 4 + x
x = -2 - 4 = - 6
x = -6
13) R(3, -5) and S(1, x)
slope = -2
We want to determine the value of x so that the line RS is parallel to another line whose slope is given as -2
Slope = (y2 - y1)/(x2 - x1)
From the information given
y2= x
y1 = -5
x2 = 1
x1 = 3
Slope = (x - -5) / (1 - 3) = (x+5)/-2
Since the slope of the parallel line is -2, therefore
(x+5)/-2 = -2
x + 5 = -2×-2
x + 5 = 4
x = 4 - 5 = - 1
