Answer:
40
Step-by-step explanation:
Simply plug in the values for X and Y and solve.
5(3) + 3(5) + 2(3) + 4
5*3=15, 3*5+15, 2*3=6, and 4 is 4.
15 + 15 + 6 + 4= 40
Answer:
$41.52
Step-by-step explanation:
38.99*0.065 = 2.53435 (2.53), 38.99 + 2.53 = 41.52
B is the most correct, then A. C and D is wrong cuz, complementary is sum of 90 degrees and there is no opposite sides are congruent
Answer:
12 centimeters
Step-by-step explanation:
The side lengths of the triangle are: 26, 28, and 30 centimeters
a = 26 cm, b = 28 cm, c = 30 cm
To find the area, we first must find the semi-perimeter with the following equation:
s = (a+b+c)/2
= (28+26+30)/2
= 42 centimeters
Now, to find the area, we can use Heron's formula:
A =
336 squared centimeters
Since the area of the parallelogram is equal to the area of our triangle:
Area of Parallelogram = Area of Triangle
base ⋅ height = 336 squared centimeters
28 ⋅ height = 336 squared centimeters
height = 336/28
height = <u>12 centimeters</u>
Answer:
35
Step-by-step explanation:
x-18=y
y*-3=-51
y=17
x-18=17
17+18=x
x=35
