Answer:
1. -49
2. -8
Step-by-step explanation:
1. For there to be infinite solutions the left and right sides must be identical.
-7(2x + 7) + 10x
= -14x - 49 + 10x
= -4x - 49
Thus the blank space must contain -49.
2. For there to be no solution the terms in x must be the same on both sides and the numbers different.
As you see the numbers are different. The answer is the x term on the left side = -8x, as the x terms on the right simplify to -8x.
-8 goes in the blank space.
X/0.5 = 24
X/0.5(0.5) = 24(0.5)
X = 12
Given the triangles ABC and DEC
For the triangle ABC:
m∠A = 36, m∠B = 21
So, the m∠C = 180 - (m∠A + m∠B ) = 180 - (36 + 21) = 123
So, comparing the measurements of the angles of both triangles:
So, the triangles are similar using the AA postulate.
So,
Answer:Width of box is not taken up by pencils = 2 5/8
Step-by-step explanation:
I assume you are saying f(x) = (-x^2 + 4x + 6) / (x+4)
