Answer:
C. since 8, 15, 17 are pythagorean triples
Answer:
135 meters
Step-by-step explanation:
h = 60t - 5t²
t is in seconds and it says to find out the height after 3 seconds
Sub the value '3' into 't'
h = 60(3) - 5(3)²
h = 180 - 5(9)
h = 180 - 45
h = 135 m
Answer:
SEE BELOW
Step-by-step explanation:
1. find value of m
a^2 + b^2 = c^2
7.5^2+10^2=c^2
15+100=c^2
115=c^2
square it
=10.7 (not answer)
a^2+b^2=c^2
10.7^2+30^2=c^2
114.49+900=c^2
1014.49=c^2
square it
m=31.9
2.20^2 + 21^2 = 841
29^2=841
yes the triangle is right angled !!!
hope this helps :)
hey mate☺️☺️ here's your answer......
4x'4 + 1
Answer:
see below
Step-by-step explanation:
-7(x+2)+4x=6(2x-4)
Distribute
-7x -14 +4x = 12x -24
Combine like terms
-3x-14 = 12x-24
Add 3x to each side
-3x-14+3x = 12x-24+3x
-14 = 15x-24
Add 24 to each side
-14+24 = 15x -24+24
10 = 15x
Divide each side by 15
10/15 =15x/15
2/3 =x
