Answer:
2b²(8b²+15b-6)
Step-by-step explanation:
16
+30b³-12b²
2b²(8b²+15b-6)
This is not further factorable. If you want to find the roots, you'd have to use the quadratic formula for the polynomial in the parentheses. Therefore that is our final answer.
Answer:
none of these are right but the answer is 2x - y = -1.
D would be right but there is a negative sign in front of 2x.
Step-by-step explanation:
The y intercept of given equation y = 2x + 10 is (0, 10)
<em><u>Solution:</u></em>
Given equation of line is:
y = 2x + 10
<em><u>To find: y intercept of the line</u></em>
The point where a line or curve crosses the y-axis of a graph is y intercept
<em><u>Finding y - intercept:</u></em>
To find the y-intercept, plug 0 in for 'x' and solve for 'y'
<em><u>Substitute x = 0 in given equation</u></em>
y = 2(0) + 10
y = 0 + 10
y = 10
Thus the y intercept of given equation is (0, 10)
Answer:
So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by
2.5/1 . Then, 20 x 2.5=50. So the answer is 50 km<-------------- Final answer

Answer:
A. D and E are similar but not congruent.
Step by step explanation :
The side lengths of D are 3 units and 1 unit. The side lengths of E are 2 units and 6 units. The sides are proportional, but are not congruent; this means that the quadrilaterals are similar but not congruent. Choice A is true and choice C is false.
The side lengths of E are 2 units and 6 units. The side lengths of F are 3 units and 1 unit. The sides are proportional, but are not congruent; this means that the quadrilaterals are similar but not congruent. Choice B is false.
The side lengths of D are 3 units and 1 unit. The side lengths of F are 3 units and 1 unit. The sides are congruent; this means that the quadrilaterals are congruent. Choice D is false.
