Answer:
x = 6
Step-by-step explanation:
The scale factor is
28/8 = 7/2
We take the ratio of the larger side over the smaller side
Using ratios we can find the sides
28 21
----- = ---------
8 x
Using cross products
28x = 21*8
28x =168
Divide each side by 28
28x/28 = 168/28
x =6
Answer:
a(
+
) = = -13
Step-by-step explanation:
Given that a = -1, b=2 and c= -3
find the value of a(+)
Just substitute the values given for each variable
a(+) = (-1)(
+
) ; do the exponents first
a(+) = (-1)(4+9)=(-1)(13) ; now add inside the parenthesis;
a(+) = -13 ; and multiply by -1
The area of a trapezoid is half its height multiplied by the sum of its two bases. So in other words 1/2h(b1+b2)
