So firstly, multiply both sides by t: $ta=v_1-v_0$

Next, add both sides by v0, and your answer will be: $ta+v_0=v_1$

For the triangles described, which of the following statements must be true? In triangle DEF, DE=8 in., DF=23 in., and ∡D=16°. I

Temka [501]

Answer:

∠Q≅∠F

Step-by-step explanation:

Two triangles are said to be congruent if all the three sides of the triangles are equal and all the three angles are equal.

Given that: In triangle DEF, DE=8 in., DF=23 in., and ∡D=16°. In triangle PQR, PQ=23 in., PR=8 in., and ∡P=16°.

Hence we can say that ΔDEF is congruent to ΔPQR. According to the side-angle-side (SAS) triangle congruence theorem: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.

Therefore:

DF = PQ, DE = PR, EF = RQ, ∠D = ∠P, ∠E = ∠R and ∠F = ∠Q

For which expression is the sum of the constants greater than the sum of the coefficients?

Svetach [21]

Answer:

$8+3x^2+7x+4$

Step-by-step explanation:

The first expression is

$7+3x^2+7x+3$

The sum of the constants is 7+3=10

The sum of the coefficients is 3+7=10

The second expression is;

$7+4x^2+4x+1$

The sum of the constants is 7+1=8

The sum of the coefficients is 4+4=8

The third expression is;

$8+4x^2+8x+2$

The sum of the constants is 8+2=10

The sum of the coefficients is 4+8=12

The fourth expression is;

$8+3x^2+7x+4$

The sum of the constants is 8+4=12

The sum of the coefficients is 3+7=10

Hence the correct choice is the expression in which the sum of the constants greater than the sum of the coefficients
