Answer:
-10w - 20
Step-by-step explanation:
You distribute the 5 to each term inside the parentheses. 5 * -2w = -10w, and 5 * -4 = -20. Then you add them to get -10w - 20.
Answer:
first triangle (to left) b=8, second one c=17
Step-by-step explanation:
for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.
A^2 + B^2 = C^2
^ ^ ^
^ ^ Hypotenuse
^ second side
first side
Substitute:
5^2 + b^2 = 9^2
SImplify:
25+b^2 = 81
Reduce:
b^2 = 64
Simplify:
b=8
In the second triangle, we are given 2 sides.
Let's do the same thing we did in the first one.
Givens:
A = 8
B = 15
Find:
C
Substitute:
8^2 + 15^2 = c^2
Simplify
64 + 225 = c^2
Reduce:
289 = c^2
Let's now square root both sides
square root of 289 is 17
so we are left with this:
c=17
Phew, you did it!
Hope this helped :))
Let a,b and c is side of a triangle where:
a = 1
b = 5
c = 11
a^2 + b^2 = c^2. if the following statement is right, then triangle have these side.
1^2 + 5^2 = 11^2
1 + 25 = 121
26 != 121 ( != means not equal to)
Therefore, triangle can't have side length of 1, 5 and 11 ft.
