A and D can be automatically eliminated since the a side cannot be longer than the hypotenuse in a triangle.
Recognize that the two triangles are similar triangles, you get
2.7/3.6 = h/1.5 => h = 1.125.
* parenthesis tell you to multiply whatever is outside them by whatever is inside them, so let’s do that!
All we need is a calculator !!
1. 0.3(p) - 0.3(3)
0.3p - 0.9
2. 1.2(0.3x) - 1.2(1.4)
0.36x - 1.68
3. -3(2x) - 3(5)
-6x - 15
4. -7(2k) - 7(-h)
-14k + 7h
5. -1/2(6x) - 1/2( -1/3)
-3x + 1/6
6. -3(0.2m) - 3(5)
-0.6m - 15
7. -0.6(0.4y) - 0.6(-1)
-.24y + 0.6
* remember that when you multiply to negatives, it equals a positive!!
Hope I helped :)
(2n - 9) - 5(-2.4n + 4) use distributive property
= 2n - 9 + (-5)(-2.4n) + (-5)(4) = 2n - 9 + 12n - 20 combine like terms
= (2n + 12n) + (-9 - 20) = 14n - 29
Answer:
10 ft, 14 ft
Step-by-step explanation:
Let b represent the length of the shorter base. Then the longer one is b+4 and the area is ...
A = (1/2)(b1 +b2)h
120 = (1/2)(b +(b+4))(10) . . . . use given values
12 = b+2 . . . . . . divide by 10, simplify
10 = b
14 = b+4
The measurements of the two bases are 10 ft and 14 ft.
The answer is if the numbers have the same base then you have to subtract or divide to change the base so the two numbers don’t have the same base
