Answer:
2
Step-by-step explanation:
Because 4x2= 8 than you add it with 8 an the answer is 16
Answer:
50.41 feet
Step-by-step explanation:
Hypotenuse = length of ladder
31 = opposite side of angle
sin(angle) = (opposite)/(hypotenuse)
sin(78) = (36)/(hypotenuse)
hypotenuse = sin(78)/ (36)
hypotenuse = 50.41 feet
length of ladder = 50.41 feet
Answer:
A = 15t +15
Step-by-step explanation:
The amounts have a common difference of $15, so that is apparently the amount Jasmine is saving each week. Week 1, however, is $15 more than $15×1. The function ...
A = 15t +15 . . . . dollars
seems to fit the data.
Answer: it is 3 • (x + 4)
Step-by-step explanation: We move all terms to the left:
4-2x+8-(+5x)=0
We add all the numbers together, and all the variables
-2x-(+5x)+12=0
We get rid of parentheses
-2x-5x+12=0
We add all the numbers together, and all the variables
-7x+12=0
We move all terms containing x to the left, all other terms to the right
-7x=-12
x=-12/-7
x=1+5/7We move all terms to the left:
4-2x+8-(+5x)=0
We add all the numbers together, and all the variables
-2x-(+5x)+12=0
We get rid of parentheses
-2x-5x+12=0
We add all the numbers together, and all the variables
-7x+12=0
We move all terms containing x to the left, all other terms to the right
-7x=-12
x=-12/-7
x=1+5/7
U have to common factor that add up to -5 but times to 4 so basically the answer would be (x+5)(x-1)= 0 then you would get
x+5=0
x-1=0
both x’s are going to be different and have to equal to zero
x=-5
x=1
for the other one u just have to get two number that multiply to -49
x^2=-49
u square root the -49 and get -7 but u have to have both a positive and negative for 7
so
x=-7
x=7
