Answer:
l think the answer is C
32.70m
Step-by-step explanation:
we all know that perimeter is the distance round the shape.
so the first step is adding 6 +6 because the other side of the shape is also 6 then add 5 and this equals to 17.
After that we find the area of the circle
which is 3.14*5= 15,7
After getting this value we add it to 17
then we get 32.70m
Answer:
-1
Step-by-step explanation:
The two numbers are 29 and -52
Further explanation:
Let x be the larger number
and
y be the smaller number
then according to given statements
Adding both equations
Putting x = 29 in first equation
<u>Proof:</u>
Putting the values of x and y in first equation
So, The two numbers are 29 and -52

Answer:
∠1 = ∠3 = ∠5 = ∠7 = 81°
∠2 = ∠4 = ∠6 = 99°
Step-by-step explanation:
Vertical and corresponding angles are congruent. Angles 1 and 99° are supplementary, so ...
∠1 = 180° -99° = 81°
Then we have ...
∠1 = ∠3 = ∠5 = ∠7 = 81°
∠2 = ∠4 = ∠6 = 99°
Answer:(k+1)(2K+7)
Step-by-step explanation:
Using the quadratic formula
X=-b±-√b^2-4ac/2a
ax^2+bx+c=0
2k^2+9k+7=0
In this case a=2,b=9,c=7
-9+-√9^2-4(2)(7)/2(2)
(-9+√25)/4=-9+5/4=-1
(-9-√25)/4=-14/4 =-7/2
X=-1,X=-7/2
So (K+1)(k+7/2)
So (k+1)(2k+7)
