Answer:
Square pyramid
Step-by-step explanation:
A square pyramid is a solid consisting of a square, a point not in the same plane as the square, and all points between them.
It can't be these
Triangle means the plane of the figure that is formed by connecting 3 particular points but it is not in a straight line. (B)(B) ← incorrectincorrect
Cube means the solid figure of having 6 square plane faces which that the angle between about 2 adjacent sides that is a right angle (C)(C) ← incorrectincorrect
Square Prism means the shape of a square that has approximately 3 dimensional shape that has a rectangular sides and shape, but it has about 2 that are square(D)(D) ← incorrectincorrect
Your answer is ↓
square pyramid (A)(A) ← CORRECT!CORRECT!
Good luck on your assignment and enjoy your day!

Answer:
B
Step-by-step explanation:
Take f(x) and plug into g(x)
(2x+1)+14 = 2x+15
Answer:
Q1: No solutions
Q2: x=2, y=-2
Q3: x=1, y=4
Step-by-step explanation:
Q1: Found out 0y = 18 which is impossible therefore no solution.
Q2:
In the first equation:
Let's express x in terms of y by changing the subject. Follow my steps.
Now let's put the x above into the second equation:
It becomes: . Follow my steps.
Put y = -2 into the first equation:
Q3:
Multiply the first equation by 3 and the second equation by 7, so that both are 21x.
1st equation:
2nd equation:
We can now substract the 2nd equation with the 1st equation so that both 21x cancels out and only the variable y remains.
Put y = 4 into the second equation to find x.
