Your answer would be 32. You add 23 + 9 and you get 32.
Answer:
length : 8 m
width : 13/2 = 6.5 m
Step-by-step explanation:
area of rectangle = l(ength)×w(idth) = 52
l = 2w - 5
=> (2w - 5)×w = 52
=> 2w² -5w - 52 = 0
we know, when transforming this quadratic equation into a multiplication of two expressions of w, that we need to have 2w and w (to make 2w²), and then which 2 numbers multiply to 52 and add to -5 (when one is multiplied by 2 due to 2w) : -13 and 4
=> (2w - 13)×(w + 4) = 0
=> 2 solutions for w :
2w-13 = 0
2w = 13, w = 13/2
w+4 = 0, w = -4
negative values for a side length of a shape do not make sense, so the only usable solution is w = 13/2
=> l = 2w - 5 = 13 - 5 = 8
You can multiply ANYTHING. Just make sure that when you multiply, you change the exponents properly. Combining like terms is basically like normal addition. For example, you cannot add 6x +3y because they have different variables. If it was 3x+6x, then you can add it because they are like terms.
Hope this helps! Comment if you have any questions!
Well, if we proceed to plan the problem like this:
<span>A = the land has oil
B = the kit is not accurate
P(A and B) = P(A) * P(B)
</span>Then we can say that <span>(0.45)(1−0.80)=(0.45)(0.20)=0.09
So the answer will be the first one.
I hope this can help you</span>
Answer:
x = -2
Step-by-step explanation:
3x + 5 + 15x + 25 + 6 = 0
18x + 36 = 0
18x = -36
x = -2
