Hi lola66795 i know the answer the answer is 415 pounds what you have to do is subtract 1585 from 2000 and you will get 415
Get it to equal 0
minus 17x from both sides
2x²-17x+35=0
tricky part
get something like
(2x-a)(x-b)
we know the signs are negative since the middle term is negative and last term is positive
so a and b are either 1 and 35 or 5 and 7
(2x-1)(x-35), nope
(2x-35)(x-1) nope
(2x-5)(x-7), nope
(2x-7)(x-5), yep
(2x-7)(x-5)=0
set to zero
2x-7=0
2x=7
x=7/2
x-5=0
x=5
x=7/2 and 5
Step 1 Distributive step 2 Multiplication property of equality step 3 Multiplication property of equality.step 4 Division property of Equality The answer would be 125=x
She enlarges by a scale factor of 1.2, so we can multiply this to all the measurements to find the sides of the enlarged triangle.
6 * 1.2 = 7.2
7 * 1.2 = 8.4
8 * 1.2 = 9.6
Now find the Area and Perimeter of the enlarged triangle.
A = 1/2bh
A = 1/2 * 9.6 * 8.4
A = 40.32
P = a + b + c
P = 7.2 + 7.2 + 9.6
P = 24
