19.95x + 9.95y <== ur answer
Answer:
See Below
Step-by-step explanation:
Thankfully, all the parts you need are given.
First, find the surface of one triangle
A = 1/2bh
A = 1/2(15)(9)
A = 1/2(135)
A = 67.5
Multiply by 4 to get the sum of all the sides.
67.5(4) = 270
Now find the surface area of one square
A = bh
A = (15)(15)
A = 225
multiply by 5 to get all 5 sides
225(5) = 1125
Add sums together
1125 + 270 = 1395
Answer:
x³ + 3x² - 46
Step-by-step explanation:
note that (f + g)(x) = f(x) + g(x)
f(x) + g(x)
= x² - 36 + x³ + 2x² - 10 ← collect like terms
= x³ + 3x² - 46
Answer:
8
Step-by-step explanation:
Let's call the center of the middle circle J, and the center of the third circle K.
Draw a line from J to the line AD such that the line is perpendicular to AD.
This forms a right triangle that is similar to the triangle ΔADK.
Writing and solving a proportion:
x / DK = AJ / AK
x / 5 = 15 / 25
x = 3
Now, draw lines from J to B and C. We now form two congruent right triangles, where the hypotenuse is 5 and the shared leg is 3.
That means these are both 3-4-5 triangles.
Therefore, BC = 4 + 4 = 8.
Answer:
LINE HJ
Step-by-step explanation:
The slop of the line you are given is 1/2. The perpendicular of that is -2/1. I got that bc it is the negative reciprocal.
