PLS HELP! 7x +10y= -23<br><br> 7x + 6y = - 39
mote1985 [20]
4y = -23 + 39
4y = 16
y = 4

Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9

x = -9
y = 4

Ben made a model (shown below) of the square pyramid he plans to build when he grows up.
elena-s [515]

Answer:

336 m^2

Step-by-step explanation:

The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:

A=A_b + 4A_t

where:

A_b=L^2 is the area of the base, where

L is the length of the base

A_t=\frac{1}{2}Lh is the area of each triangular face, where

h is the height of the face

Substituting,

A=L^2+2Lh

For the model in this problem,

L = 12

h = 8

Therefore, the surface area here is:

A=12^2 +2(12)(8)=336

I need a bit of help here.
kotykmax [81]

Answer:

Beginning in the 6th century BC with the Pythagoreans, the Ancient Greeks began a systematic study of mathematics as a subject in its own right with Greek mathematics. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.

Step-by-step explanation:

The first recorded zero appeared in Mesopotamia around 3 B.C. The Mayans invented it independently circa 4 A.D. It was later devised in India in the mid-fifth century, spread to Cambodia near the end of the seventh century, and into China and the Islamic countries at the end of the eighth.
