Answer:
297 ft squared
Step-by-step explanation:
find the area of the triangle, which is (bh)/2
(22*7)/2=77
find the area of the rectangle (bh)
22*10=220
add
77+220=297

Step-by-step explanation:
Answer:
548
Step-by-step explanation:
1) Divide 137 by 0.25 (25%)
137/0.25 = 548.
To check, find 25% of 548.
(548 x 25)/100 = 137
First square both sides
1-3x=(x+3)^2 use foil to unfactor it
1-3x=x^2+6x+9 subtract 1 from both sides
-3x=x^2+6x+8 add 3x to both sides
0=x^2+9x+8
Now that we got it equal to zero you have to factor the new trinomial
0=(x+1)(x+8)
Now since both are being multiplied by each other, if you get 1 of them to equal zero then both equal zero since 0 times anything equals 0.
So your solutions are x=-8 and x=-1
