Answer:
OA) 14
Step-by-step explanation:
2((7+1)-1)
2(8-1)
You could expand the brackets then simplify or just simplify now. It will be better to simplify now though but I will do both methods.
Simplifying first:
2(7) = 2 × 7 = 14
Our answer is 14 So answer is OA) 14
Expanding first then simplifying:
2(8-1) = 16-2 = 14
Our answer is 14 So answer is OA) 14
Answer:
52 cm
Step-by-step explanation:
Use the pythagorean theorem to solve for missing sides in a right triangle.
20²+48²= missing side
20²+48²=2704
Take the square root of 2704 to get the missing side.
Answer:
Step-by-step explanation:
The given equation is :
We need to find the value of x.
When the exponent 2 removes from LHS, it will shift to RHS as square root as follows :
We know that, 4×4= 16 and 5×5 = 25
So,
So, the solution of the given equation is 4/5.
Answer:
De value of k is 9
Step-by-step explanation:
6,-1
b(1,3)
(k,8)
am using bodmas
a6-1×1=6a
b1×3=3b
abc=8
6a+3b+8=17-8
=9

Answer: 9</h3>
================================================
Work Shown:
a = unknown = leg #1
b = 12 = leg #2
c = 15 = hypotenuse
Plug those values into the pythagorean theorem and solve for 'a'
a^2 + b^2 = c^2
a^2 + (12)^2 = (15)^2 .... substitution
a^2 + 144 = 225
a^2 = 225 - 144 ... subtracting 144 from both sides
a^2 = 81
a = sqrt(81) .... applying square root to both sides
a = 9
