Answer:
40 cm and 42 cm
Step-by-step explanation:
Two leg length: x and x+2
x² + (x+2)² = 58²
2x² + 4x + 4 = 3364
2x² + 4x - 3360 = 0
(x+42) (x-40) = 0
leg length is a positive number so x = 40
another leg = 42
The probability that an event occurs is the number of times it could occur compared to the total number of possible events, assuming the probability of each event occurring is equal.
John has
coins total. If 4 of the coins are dimes, the probability that he draws a dime is
.
Answer:
You included no options so I will list some of the various fractions and decimal that are equivalent to the fraction of days it was cloudy in April.
In fraction form, the value can be simplified to;
In decimal form, the value would be;
= 12 ÷ 30
= 0.4
Y=x^2+3x+4
y-x=7
x^2+3x+4-x=7
x^2+2x+4=7
(factor) x^2+2x-3=0
(x+3)(x-1)=0
X= -3 and X=1
(Plug x in for y)
Y= 1^2+3(1)+4
Y=8
(Check your answer on the second equation)
8-1=7
7=7 (Which is the solution)
The other number is 8 because 8 x 4 = 32
