First do distributive property
2x + 10 + 3x = 30
Now combine like terms
5x + 10 = 30
Subtract 10 from both sides
5x = 20
Divide both sides by 5
x = 4
It’s 6x6=36, because if 4 over 2 was 4 twice then 6 over 2 is 6 twice.
The surface area is the area of all the surfaces. Let's find the area of the square and the four triangles and add them together:
Square:
Triangles 1, 2, 3, & 4:
Now add them all up:
So the surface area of the square pyramid is 340 square inches.
Answer:
t ≤ -135
Step-by-step explanation:
multiply each side by 5 which then cancels out the 5 in the fraction then turns -27 into -135. Since we multiplied negatives we flipped the sign.
Answer:
x=14/3
Step-by-step explanation:
According to the corresponding angles theorem, when parallel lines are cut by a transversal, the corresponding angles are congruent. These 3 lines are all parallel, so 70 = 12x +14.
Subtract 14 from both sides
56 = 12x
Divide both sides by 12
14/3 = x
x=14/3
