Answer:
simple follow me
Step-by-step explanation:
2(4y-7)+9y=-31
8y-14+9y=-31
<u>y=</u><u> </u><u>-</u><u>1</u><u>7</u>
<u>x=</u><u> </u><u>-</u><u>7</u><u>5</u>
Answer:
substitute the value of x with ( a+2 )
Area=1/2 times base times height
area=60
height=12
60=1/2 times base times 12
divide both sides by 12
5=1/2 times base
multipy both side sby 2
10=base
10 units=base
