3r = 10 + 5s
Put the value of r = 10 to the equation and solve it for s:
3(10) = 10 + 5s
30 = 10 + 5s <em>subtract 10 from both sides</em>
20 = 5s <em>divide both sides by 5</em>
4 = s → s = 4
<h3>Answer: for r = 10, s = 4.</h3>
Answer:
-6
Step-by-step explanation:
h(x) = -3x – 12 becomes h(-2) = -3(-2) – 12 = -6
Among the congruent quadrilaterals, the segment that must also measure 3 cm is: A. A F.
<h3>What are Congruent
Quadrilaterals?</h3>
Congruent quadrilaterals have corresponding congruent angles and sides.
Given that, GHJK ≅ ASDF and GHJK ≅ VBNM, it means that all corresponding sides and angles are equal to each other.
MV corresponds to KG and A F. If MV = 3 cm, then one segment that must measure 3 cm is:
A. A F

Secant and tangent theorem: Square of measure of tangent is equal to the product of length of whole secant and length of exterior secant segment, i.e.
.
The whole secant wuth exterior secant 4 cm is 4+x cm. Tangent is 7 cm. Using previous theorem, you can get that
.
Solve this equation:
cm.
Answer: x=8.3 cm.
