Answer:
a=9in
Step-by-step explanation:
Pythagoreans Theorem
a^2+5.6^2=10.6^2
a^2+31.36=112.36
a^2=81
(take square root of both sides)
a=9
3(2t+5)=5t+25
Multiply the bracket with 3
(3)(2t)(3)(5)=5t+25
6t+15=5t+25
Move 5t to the other side. Sign changes from +5t to -5t
6t-5t+15=5t-5t+25
6t-5t+15=25
Move +15 to the other side. Sign changes from +15 to -15
6t-5t+15-15=25-15
6t-5t=10
1t=10
divide by 1
1/1t=10/t
t=10
Answer: t=10
Answer:
Area= 80 in square
Step-by-step explanation:
h=8
b=20
formula= b*h/2
so, 8*20/2
Area= 80 in square
