Answer:
68
Step-by-step explanation:
- We have to find area first:
Flower bed: (triangle)
A =
1/2 × 3 × 8
3 times 8 is 24, time 1/2 is <u>12</u>
Vegetable Patch: (trapezoid)
A =
5 + 7 = 12
12 / 2 = 6
6h or 6 × 10 = <u>60</u>
Whole Garden:
14 × 10 = 140
2. Then we subtract.
140 - 72 is 68
The determinant is found by the formula ad-cb
where the letters are: a and b is the top row and c and d is the bottom row
so ad = 12*2 and cb = -6*0
12x2 = 24
-6x0 =0
24-0 = 24
the determinant = 24
Answer:
1,116 USD
Step-by-step explanation:
1=1.55 that is a 55% increase. 55% of 720 is 396. 720+396=1,116 USD
Answer:
84x¹²
Step-by-step explanation:
To simplify this expression, we work from left to right:
4x(-3x⁸)(-7x³)
Multiplying the coefficients of the first two, we have 4(-3) = -12. Using the laws of exponents, multiplying powers with the same base means we add the exponents; this gives us x(x⁸) = x¹⁺⁸ = x⁹. This gives us
-12x⁹(-7x³)
Multiplying the coefficients, we have -12(-7) = 84. Using the laws of exponents, for the variable we have x⁹(x³) = x⁹⁺³ = x¹²
This gives us
84x¹²
The answer would be 168 because Sam’s own age is 56 and his father was 3x older than him so u have to use 56x3=168. Babam u got urself an answer
