Answer:
the value of h on the diagram is 9cm
Step-by-step explanation:
area = 1/2 * base * height
a = 1/2*b*h
36=1/2*8*h
36=4h
since the 1/2 will multiply the 8
36=4h
multiply both sides by 4
h=9cm.

<em><u>Solution:</u></em>
Given that, Jennifer had 7/8 foot board she cut off 1/4 foot peice that was for a project
To find: Board that was left
From given,


Remaining feet of board is found by finding the difference between total length of board and foot that was cut off

Substituting the values we get,

Thus
feet board is left
Step-by-step explanation:
T3=8
8=a+2d
where a is first term ,d is common ratio
8=a+2(2)
8=a+4
a=8-4
a=4
first term T1 is 4
T2=a+d
T2=4+2
T2=6
T4=a+3d
T4=4+3(2)
T4=4+6
T4=10
T5=a+4d
T5=2+4(2)
T5=4+8
T5=12
4,6,8,10,12
Answer:
(a^2)+4a-5
Step-by-step explanation:
(3+a+2)(a+2-3)
(a+5)(a-1)
use FOIL or box method
5a-5+(a^2)-a simplifyes to
(a^2)+4a-5
the correct answer is c 78
Step-by-step explanation:
lit can't be a because to small and can't be b because also to small. and and 92 is uptus and this is an acute angle
