For this question you should say:
75/100 = 12/?
so the ? is your answer:
12*100/75 = 16 :)))
I hope this is helpful
have a nice day
Answer:
x = 1 ±√89
Step-by-step explanation:
We have the equation:
(x+7)(x-9) = 25
Using distributive property:
x(x-9) + 7(x-9) = 25
x²- 9x + 7x - 63 -25 = 0
x²- 2x - 88 = 0
To complete squares we need to add and subtract 1, as follows:
x²- 2x - 88 +1 -1 = 0
x²- 2x +1 -88 -1 = 0 (this is a perfect square)
(x - 1)² - 89 = 0
Solving for x:
(x - 1)² = 89
x - 1 = ±√89
x = 1 ±√89
The answer is 78
If you multiply 17x6 you get 102
102 equals the whole rectangle after that you need to get rid of the part that’s not there
so you multiply 8x3 which equals 24
you then subtract 24 from 102 and get 78
Answer:
a) 
b) -4.99
d) 1.9435
Step-by-step explanation:
We are given certain rule to identify number. We have to identify from the entries that can be interpreted as numbers.
a) 1.56e-9
This a number as there are no spaces, no comma, no units.
b) -4.99
This a number as there are no spaces, no comma, no units.
c) 40O0
This is not a number as 0 is substituted by O.
d) 1.9435
This a number as there are no spaces, no comma, no units.
e) 1.56 e-9
This is not a number as it contains a space.
f) $2.59
This is not a number as it contains a dollar sign.
g) 3.25E4
This is not a number as it contains alphabet.
h) 5,000
This is not a number as there is a comma in the given.
i) 1.23 inches
This is not a number as it contains a unit.
Answer: A=70 square units
Step-by-step explanation:
The area of a triangle can be found using the formula 
Let 5=h and 7=b
Plug in the values and solve


However, since four of these triangles make up this rhombus, we can multiply the area of one of these triangles by four to find the area of the whole rhombus.
