katovenus [111]

Answer:

x = - 3

y = 4

Step-by-step explanation:

x + y = 1 | (-3)

x + 3y = 9

- 3x - 3y = - 3

x + 3y = 9

_____________

- 2x = 6

2x = - 6

x = - 3

- 3 + y = 1

y = 1 + 3

Insert 2 geometric means between -32 and 4

denis23 [38]

Answer:

16, -8

Step-by-step explanation:

Let the terms of the geometric sequence be $a, ar, ar^2, ar^3$ .

We know that $a=-32$ and thus, $-32r^3=4 \implies r=-1/2$ .

This means $ar=(-32)(-1/2)=16$ and $ar^2=-32(1/2)^2=-8$ .

Construct a quadrilateral ABCD in which AB = 4 cm, BC = 7 cm, angle A = angle C = 105 degree

Lelu [443]

Answer: see attachment

Step-by-step explanation:

Since A = C = 105° and D = 60°,

then A + B + C + D = 360°

105° + B + 105° + 60° = 260°

B + 270° = 360°

B = 90°
