I can't understand it can you explain it in English
The common difference is 2
Answer:
3.Area=πr²
d=14ft
r=7 ft
22/7*7*7
area=154ft²
5.area =1/2 bh
h=13cm
area=32.5cm²
32.5=1/2*13*b
32.5=13/2b
=5.0 or 5
base=5cm
Step-by-step explanation:
Answer:
22mm
Step-by-step explanation:
Elimination
2x+2y=10
2x-3y=5
multiply first equatn by -1
-2x-2y=-10
add to second equation
2x-3y=5
<u>-2x-2y=-10 +
</u>0x-5y=-5
-5y=-5
divide both sides by 5
-y=-1
muitply b-1
y=1
subsitue
2x+2y=10
2x+2(1)=10
2x+2=10
subtract 2
2x=8
divide 2
x=4
x=4
y=1
solution in (x,y) form is
(4,1)
