Solve each problem and show the work for each one.

Cerrena [4.2K]

Answer:

Solve by factoring.

1. 2x^2+9x+26=-4x+5

2x²+9x+4x+26-5=0

2x²+13x+21=0

doing middle term factorization

2x²+7x+6x+21=0

x(2x+7)+3(2x+7)=0

(2x+7)(x+3)=0

either

x=-7/2

or

x=-3.

3x^2-6x-4=0

comparing above equation with ax²+bx+c=0

we get

a=3

b=-6

c=-4

By using quadratic equation

x= $\frac{ - b±\sqrt{ {b}^{2} - 4ac } }{2a}$

Substituting value

x= $\frac{ 6±\sqrt{ {-6}^{2} - 4*3*-4 }}{2*-4}$

x= $\frac{ 6±\sqrt{ {84}}}{-8}$

x= $\frac{ 6±2\sqrt{ {21}}}{-8}$

-8x=6±2√21

taking positive

-8x=6+2√21

x= $\frac{6+2√21}{-8}$

x=- $\frac{3+√21}{4}$

taking negative

-8x=6-2√21

x= $\frac{6-2√21}{-8}$

x=- $\frac{3-√21}{4}$

What is the vertical distance from the origin to the point (2,9)

Ksenya-84 [330]

Answer: The answer should be 9.2195

Step-by-step explanation:They tell us the point is 2.9 and they are asking the distance from the origin which is zero. So we can use pythagorean theorem. A²+B²=C² Look at it as a triangle. They have given us A and B, so you can find C² using those information. If you plot the point in the line you know that A=2 and B=9. Using the formula will be 2²+9²=C² ⇒ 4+81=C² ⇒ 85=C². To get rid of the power of 2 in c we have to square both side to cancel it out. C would equal 9.2195

deff fn [24]

Answer: masses are 825 g and 1125 g

Step-by-step explanation: masses of hamsters are x and x+ 300 g.

Total mass is x+(x+300) = 1950

2x = 1650 g and x= 825

1. SIMPLIFY EACH EXPRESSION:

natka813 [3]

Answer:

1. 8x2 - 7x + 4x3 - 2-3x2 + 9x - 4 = 16+2x

Step-by-step explanation:

1. Multiply all the multiplication problems (should look like this --> 16-7x+12-2-6+9x-4)

2. Calculate the sum or difference (should end up looking like this --> 16-7x+9x) and then into this (16 +2x)

Bringing us to the answer → 16 + 2x!
