The answer is 27 i think..
Answer:
9. 108 cm^2 or B
10. 1,080 m^2 or B
Step-by-step explanation:
9.
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=3·8+4·8+5·8+1
2·﹣34+2·(3·4)2+2·(3·5)2﹣44+2·(4·5)2﹣54
= 108
10.
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=15·24+8·24+17·24+1
2·﹣154+2·(15·8)2+2·(15·17)2﹣84+2·(8·17)2﹣174
= 1080
Answer:
Solving for x gives x=7
Step-by-step explanation:
First lets rewrite our equation clear, which from the question reads as :
Eqn(1).
This is a case of an equation with one variable <em>(i.e. one uknown)</em> denoted as .
The question is asking as to solve this equation and obtain the value of .
To do so we start by rewriting and simplifying the equation as follow:
which is the same as
Here we have a fraction on the left hand side reading as and an integer on the right hand side as . Thus we move the denominator of the fraction, in this case to the right hand side where we multiply it with , to eliminate our fraction and solve for as follow:
(Note how we transferd from the left hand side to the right hand side, the sign changed from <em>negative </em>to <em>positive). </em>
