Answer:
25.2
Step-by-step explanation:
A calculator will evaluate this for you. If you don't have one, you can use a Google search box.
The Order of Operations tells you to start evaluation with the inner parentheses. Multiplication is performed before addition.
2(7 +2(2.8))
= 2(7 +5.6)
= 2(12.6)
= 25.2
Base=x+7 Height=x Area=60. 60=((x+7)(x))/2----->60=(x^2+7x)/2
120=x^2+7x X^2+7X-120=0. QUDRATIC FORMULA: -7+/- SQRT(49+480)/2
(-7+/-23)/2... 8 and -15. -15 ISNT the answer because you cant have a negative length. X=8 Base=8+7---->15 Height=8
Answer:
Answer
Let height =h
Total surface area=2πr(r+h)
r=7cm
⇒968=2×
7
22
×7(7+h)
⇒
44
968
=7+h
⇒h+7=22
⇒h=22−7
=15cm.
