Mathematics
1 answer:
tangare [24]2 years ago
8 0

Answer:

no solution

Step-by-step explanation:

- 4(x + 2) = - 4x - 5 ← distribute parenthesis on left side by - 4

- 4x - 8 = - 4x - 5 ( add 8 to both sides )

- 4x = - 4x + 3 ( add 4x to both sides )

0 = 3 ← False statement

This indicates the equation has no solution

The difference of two numbers is more than 12,and one of the numbers is 3
klio [65]
X+y = 12
x-y = 3
x = 3+y

Substitute it in 1st equation,
3+y+y=12
2y = 9
y = 4.5

Substitute it in 1st eq.,
x = 12-4.5 = 7.5

So, the two numbers are 7.5 & 4.5

Hope this helps!

Let's say we have a triangle with sides called a, b, and c, and that b is the base. Our triangle has a height that we'll call h.
Irina18 [472]

Answer:

16.34 square inches.

Step-by-step explanation:

Given:

Base of triangle, b = 3 inches

Height of triangle, h = 10.89 inches

Question asked:

What is the area of this triangle in square inches?

Round your answer to the nearest hundredths place .

Solution:

As we know,

Area\ of\ triangle =\frac{1}{2} \times base\times height

                           =\frac{1}{2} \times3\times10.89\\\\ =\frac{32.67}{2} \\\\ =16.335

As, we have to find the answer to the nearest hundredths place, hence the area of triangle will be 16.34 square inches.
