Answer:
Step-by-step explanation:
Given
Required
Represent as an equation;
Expand the above
<em>Recall that b = $10 ----given</em>
becomes
3x-15=51
3x=36
X= 12
Thus the number is 12
Answer:
the answer would be A because of the x+6 so the for a is the one that starts on 6
Step-by-step explanation:
Draw a diameter through the center of the circle. Any radius of this circle is 1/2 the length of the diameter. Thus, if we divide the diameter into two equal parts, we have two lengths that form the ratio 2:1, where 2 represents the diameter and 1 the radius.
3x(9x² + 11x - 5) + 2(2x³ + 11x - 5x²) - 5x² + 8
Simplify.
27x³ + 33x² - 15x + 4x³ + 22x - 10x² - 5x² + 8
Add like terms.
(27x³ + 4x³) + (33x² - 10x²) + (-15x + 22x) + 8
Simplify.
31x³ + 23x² - 7x + 8
