SIMPLIFY 7/10+1/4-1/5=

Mathematics
1 answer:
Strike441 [17]3 years ago
4 0

Answer:

3/4

Step-by-step explanation:

Q = \frac{7}{10} +\frac{1}{4} -\frac{1}{5}      

{the smallest common multiple of 10, 4 and 5 is 5×2×2 = 20 (denominator)}

Q =\frac{7×2}{10×2} +\frac{1×5}{4×5} -\frac{1×4}{5×4}

=\frac{14}{20} +\frac{5}{20} -\frac{4}{20}

=\frac{14+5-4}{20}

=\frac{15}{20}

=\frac{3×5}{4×5}

=\frac{3}{4}

What I do to factor is find _x_=-16 and _+_=-6. -8x2=-16 and -8+2=-16. The coordinates for z if you were to graph this would be (8,0) and (-2,0)

If you cut away a triangle of area 59 cm² from a square, the remaining area will be 85 cm². Find the length of the side of the s
siniylev [52]
So the square was fine, then the triangle decided to go for a hike.

now, if the triangle when it took off, it took 59 cm², and the square was left all by its lonesome with only 85 cm², that means with the triangle in it, the square is then 59 + 85 cm², or 144 cm².

\bf \textit{area of a square}\\\\
A=s^2\qquad 
\begin{cases}
s=\textit{length of a side}\\
---------\\
A=144
\end{cases}\implies 144=s^2
\\\\\\
\sqrt{144}=s
\implies 12=s

X2+5x=-2x-12 solve for x
BARSIC [14]
X² + 5x = -2x -12
Add 2x to each side.
x² + 7x = -12
Add 12 to each side.
x² + 7x + 12 = 0
Let's solve this quadratic by factoring.
We want two numbers that add to get 7 and multiply to make 12. These are 3 and 4.
Split the middle of the quadratic.
x² + 3x + 4x + 12 = 0
Factor the first two and last two terms.
(You should get the same thing inside the parentheses.)
x(x+3) + 4(x+3) = 0
(x+4)(x+3) = 0
Any value of x which causes either factor to equal 0 is a solution.
We can derive the following equations and solutions:
x+4 = 0 ⇒ x = -4
x+3 = 0 ⇒ x = -3
