790
1) Since it's been given the expression 6x³+8x, let's plug into that the value for x=5
6x³+8x <em>Plug into that x =5</em>
6(5)³+8(5)
6(125) +8(5) <em>Distribute the factors</em>
<em>790</em>
<em />
2) So the answer is 790
Answer:
1. Construct a segment XY on the a sketch.
2. Elsewhere on the sketch, draw a line and create a point on the line . Label the point P.
3. Select point P and line segment XY. Construct circle by center and radius.
4. Select the circle and line, then construct point of intersection. Label one of the points of intersection point Q.
5. Select point P and point Q. Construct segment PQ.
6. Select the circle, line, and other point of intersection. Hide objects. Only segment XY and segment PQ should be visible on the sketch.
7. Try dragging point X. Segment PQ should lengthen and shorten as segment XY does.
Answer:
B) ∠A ≅ ∠A
Step-by-step explanation:
the reflexive property of congruence states that an angle, line segment, or shape is always congruent to itself.
so if an angle ∠A is an angle, then.∠A≅∠A.

Answer: it contains 200 grams of zinc.
Step-by-step explanation:
Ratio of zinc to copper is 4 to 15 = 4;15
Total ratio = 4+15= 19
We first find amount of both zinc and copper( the whole chemical) which is equal to
ratio of copper / total ratio x (the entire chemical--total grams of zinc and copper) =amount of copper
15/19 x X = 750
X= 750 X 19 / 15= 950 grams
To find amount of zinc in the chemical = ratio of zinc / total ratio x total amount of chemical
=4/19 x 950
=200 grams
Y=-3x+1 this is the answer I think
