Answer:
Step-by-step explanation:
is the answer to almost anyway that you can solve this problem.
Multiply the numerator and denominator by the conjugate.
Answer:
(x^2 - 4)(x^2 - 3)
Step-by-step explanation:
Let y equal to x^2. We can rewrite the expression as:
y^2 - 7y + 12
Now, we have to look for numbers that have a product of 12 and a sum of -7. These numbers are -3 and -4. We can factor the equation:
(y - 4)(y - 3)
Now, we can substitute x^2 back in(we defined y as x^2 before):
(x^2 - 4)(x^2 - 3)
-7 is the y-intercept. 2 is the slope. Rise over run.

<span>54.08 * 0.08 </span>
<span>(total) * (sales tax, percent in decimal) </span>
<span>== $4.33 (4.3264) (tax) </span>
<span>Second Step: </span>
<span>54.08 + 4.33 </span>
<span>(total) + (tax) </span>
<span>== $ 58.41 </span>

1.
a. 8 x 7 x 1/2 = 56 x 1/2 = 28
b. 24 x 14 x 1/2 = 336 x 1/2 = 168
c. 5 x 12 x 1/2 = 60 x 1/2 = 30
d. 4 x 4.8 x 1/2 = 19.2 x 1/2 = 9.6
2.
two triangles: 2(4 x 8 x 1/2) = 4 x 8 = 32
rectangle: 15 x 8 = 120
total area: 32 + 120 = 152
