Rose 40%
original=100%, now it is 140%
140% of original=now
140% of orignal=350
1.4 of original=350
divide both sides by 1.4
original=250
answer is C
other way
350/140=x/100
35/14=x/100
times both sides by 1400
3500=14x
divie both sides by 14
250=x
C is answer
Answer:
Step-by-step explanation:
15) tanA = 6.8/3.0
16) tanR = 9/24
17) tanB = 16/17
18) BC = 10tan40
19) PQ = 38/tan75
20 BC seems to be missing some of its length number I will call it 14
redo if that is incorrect.
∠A = arctan(14 / 14.5)
∠C = arctan(14.5 / 14)
Answer:
x=6
Step-by-step explanation:
divide each term by 2 then simplify
Answer:
129
Step-by-step explanation:
(4*2^2+8*2)= 32
(3*2^2-5*2+20)=22
(7*2+30)=44
32+31+22+44=129
Answer
5.0/5

carlosego genius 11.6k answer 175.7m people helped the perimeter is the sum of the sides: P=(x-7) +(x+1)+(x) rewriting: P=3x-6 the area is giving by:A=(1/2)*(x-7)*(x) the area and the perimeter are the same: (1/2)*(x-7)*(x)=3x-6 rewriting: (x-7)*(x)=6x-12 x^2-7x-6x+12=0 x^2-13x+12=0 polynomial of degree 2, therefore there are 2 possible solutions. Viable solution. Viable solution: x=12 sides of triangle: 5 12 13
