Helen [10]3 years ago
3 0

Answer:

Step-by-step explanation:

1) (x+2)(x+2)=-x-2

x^{2} +2x +2x +4+=-x-2

x^{2}+4x+4+x+2

x^{2}+5x+6

2) x^{2} +4x +12 -16x +24=0

x^{2} -12x+36=0

3) (x-4)(x+1)

x=4 and/or x=-1

4) (x-5)(x-6)

x=5 and/or x=6

5) (x-7)(x+2)

x=7 and/or x=-2

6) x^{2}+3x-10=0

(x-5)(x+2)

x=5 and/or x=2

7) x^{2}+x-20

(x-5)(x+4)

x=5 and/or x=-4

Adam had silly putty 4 5/6 inches long. If he stretched it 2 2/3 times it's current length how long would it be?
Nikitich [7]
You multiply the 2 together 4 5/6 and 2 2/3. 
4 5/6=29/6
2 2/3=8/3 
you multiply the tops together then the bottoms together
29*8=232
3*6=18
232/18=116/9

Where on the graph of 2x - 6y = 7 is the x-coordinate twice the y-coordinate?
Nikolay [14]

Answer:

The required point is P(-7,\frac{-7}{2}) where, x-coordinate twice the y-coordinate on line 2x - 6y = 7

Step-by-step explanation:

Given equation of line is 2x-6y=7

To find point on graph whose x-coordinate twice the y-coordinate:

Let y be y-coordinate of point

Hence, x-coordinate of point will be 2y

The required point is P(2y,y) on equation of line 2x-6y=7

Now,

2x-6y=7

2(2y)-6y=7

-2y=7

y=\frac{-7}{2}

Thus,

The required point is P(-7,\frac{-7}{2})

Note: Figure show equation of line red line and point P as blue dot.

If line AD is a tangent to circle B at point C, and m∠ABC = 40º, what is the measure of ∠BAC? 90º  180º   50º   40º
zhenek [66]
We have a line tangent to the circle with center B at point C. We know that the angle formed between the tangent line at the point of intersection to the line extended from that point to the center of the circle is equal to 90°. In the problem, the 90° is for ∠BCA. We also know that the summation of all angles in a triangle is 180°. We have the solution below for the ∠BAC
180°=∠BAC + ∠BCA + ∠ABC
180°=∠BAC + 90° + 40°
∠BAC =50°
The answer is 50°.
