What you can do is see it like this 20x50 or take 5x2 which is 10 and then count how many zeroz there are in the original equation and add them. Since there are 2 zeros you add them to the 10, so the answer will be 1000.
Answer:
Step-by-step explanation:
100 + 20 = 120
- A. 5(20 + 3) = 115 ≠ 120
- B. 10(10 + 10) = 200 ≠ 120
- C. 5(95 + 4) = 495 ≠ 120
- D. 5(20 + 4) = 120, correct
(a)
= 400
(b)
(c) Only the positive solution makes sense because you cannot have a negative side length.
(d) Since one side of the painting is 20 inches, all four sides together will be 20*4 = 80 inches
Answer: The correct congruence statement is .
Explanation:
It is given that A triangle Q D J. The base D J is horizontal and side Q D is vertical. Another triangle M C W is made. The base C W and side M C are neither horizontal nor vertical. Triangle M C W is to the right of triangle Q D J.
The sides Q D and M C are labeled with a single tick mark. The sides D J and C W are labeled with a double tick mark. The sides Q J and M W are labeled with a triple tick mark.
Draw two triangles according to the given information.
From the figure it is noticed that
So by SSS rule of congruence we can say that .
Answer:
The answer is 8 units! Hope this helps!
Step-by-step explanation:f the length of any one side of the square is x, then the area is x2, and the perimeter is 4x. If the area is twice the perimeter, x2 = 2(4x), and x2 − 8x= 0. By factoring, we see this equation is equivalent to x(x − 8) = 0, which has solutions 0 and 8. The length cannot be 0, so it must be 8 units.
