Whats 2-(-4) as an addition equation
Answer:
2+4
Two negatives cancel out for a positive. Think: subtraction is just finding the difference, the total difference between them would be the same as doing 2 + 4, or 6
how can I solve this problem?
90 of 40 proportions
Please help!!!!!!!:>
Answer:
answer is (x+16)(x-3) I'm sure
______________________________
1.) Factor the expression by grouping:
- First, the expression needs to be rewritten as [tex]x^2+ax+bx-48[/tex]. To find a and b, set up a system to be solved:
[tex]a+b=13[/tex][tex]ab=1(-48)=-48[/tex]2.) List all such integer pairs that give product −48:[tex]-1,48[/tex][tex]-2,24[/tex][tex]-3,16[/tex][tex]-4,12[/tex][tex]-6,8[/tex]3.) Calculate the sum for each pair:[tex]-1+48=47[/tex][tex]-2+24=22[/tex][tex]-3+16=13[/tex][tex]-4+12=8[/tex][tex]-6+8=2[/tex]4.) The solution is the pair that gives sum 13:[tex]a=-3[/tex][tex]b=16[/tex]5.) Rewrite [tex]\bold{x^2+13x-48}[/tex]:[tex]x^2+13x-48=(x^2-3x)+(16x-48)[/tex]6.) Factor out [tex]\bold{(x)}[/tex] in the first and 16 in the second group:[tex]x(x-3)+16(x-3)[/tex]7.) Factor out common term [tex]\bold{x-3}[/tex] by using distributive property:[tex](x-3)(x+16)[/tex]
So your answer is [tex]\bold{(x-3)(x+16)}[/tex] or [tex]\bold{(x+16)(x-3)}[/tex].

What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given that A cell phone plan costs $0.20 cents per minute.
Lisa has budgeted $35 a month for her cell phone.
We need to find how many minutes Lisa can use each month.
Let us form a proportional equation to find this.
Let x be the number of minutes Lisa can use each month.
0.20/1=35/x
Apply cross multiplication
x=35/0.2
x=175
Hence, 175 minutes Lisa can use each month.

Answer:
54 m^2
Step-by-step explanation:
Area = 1/2 * base * height
You are missing height, but because you have the hypotenuse, you can use the Pythagorean Theorem to find it.
height^2 + (9m)^2 = (15m)^2
height = sqrt(225 m^2 - 81 m^2)
height = sqrt(144 m^2) = 12m
Area = 1/2 * 9m * 12m = 54 m^2
6. What is the greatest common factor of the following expression? *
15y3 – 40y
Answer:
I'm not sure what 15y3 is, but I'll take a guess.
If the only numbers are 15, 3, and -40, then the greatest common factor is 1.
If the only numbers are 15 and 3, then it's three.
If the only numbers are 15 and -40, it would be 5.
