a) 20 cm
a2 + b2 = c2
a2=12cm=144cm
b2=16cm=256cm
c2=?=?
144cm+256cm=c2
144cm+256cm=400cm
c2=20cm
400's square root is 20cm.
b) 34 cm
p2 + q2 = r2
p2=16m=256m
q2=30m=900m
r2=?=?
256m+900m=r2
256m+900m=1156m
r2=34cm
1156's square root is 34cm.
Question # 4.
a) 9.2 cm
x2 + y2 = z2
x2=6cm=36cm
y2=7cm=49cm
z2=?=?
49cm + 36cm = z2
49cm + 36cm = 85
z2 = 9.2 cm
85's square root is 9.2 cm.
b) 13.6 cm
b2 + c2 = d2
b2=8cm=64cm
c2=11cm=121cm
d2=?=?
64cm + 121cm = d2
64cm + 121cm = 185cm
d2=13.6cm
185's square root is 13.6 cm.
goodjob Kathleen but i was kind of confused at question 3 because i didn't know the question so you should put that in but than that your scribe was very good.
ReplyDeletei agree with kamille on question 3.
ReplyDeleteand also on question 4.. you lost me there. shouldnt it be like :
a)
x² + y²= z²
6² + 7²= z²
(6x6) + (7x7) = z²
36 + 49 = z²
85 = z²
√85 = √z²
9.2 = z²
kk, i wont put part b, because ill let you do do it yourself part a, was just an example.
