Answer:
<h2>14cm</h2>
Step-by-step explanation:
Given a length of the diagonal of a square modeled by the equation
d = 1.4x^1/2 where x is the area of the square, to find the estimate of the length of the square if area is 100cm², we will substitute x = 100 into the modeled equation to get s as shown;
<em>Hence the length of the diagonal of the square using the modeled equation is 14cm</em>
Answer:
x=9
y=3
Step-by-step explanation:
since all three sides of an equlateral triangle are equal:
3x+y=30 then y=30-3x
4x-2y=30
4x-2(30-3x)=30
4x-60+6x=30
10x=90
x=9
3x+y=4x-2y
x=3y
y=3
Answer: do you mean gram or gallon??
Step-by-step explanation: if gallon then a gallon is more than 1 oz. If it is gram then 1 oz is more
Hello from MrBillDoesMath!
Answer: Choice C
Discussion:
The y-intercepts are the x values where y = 0. Substituting y = 0 in the equation gives
(x+2)^2 + (0-4)^2 = 13 =>
(x+2)^2 + 16 = 13 =>
Subtract 16 from both sides
(x+2)^2 = 13 - 16 = -3 (*)
The square of a real number is greater than or equal to 0. (Not true for complex numbers). The left side of (*) is therefore >= 0 but as also equals -3. This is not possible so there is no solution to the equation. Choice C.
Thank you,
