5x + 4 + 2x + 5
First add the like terms.
You will get this: 7x + 9
And these can't be simplified anymore because they do not both go into the same multiple.
So your answer will be:
7x + 9
Answer:
i think it would be 200
Step-by-step explanation:
Two angles that sums to 180° is supplementary.
Two angles that sums yo 90° is complementary.
The numbers are "x" and "y", therefore, we suggest this system of equations:
x-y=14
xy=1800
We can solve by substitution method.
x=14+y
(14+y)y=1800
14y+y²=1800
y²+14y-1800=0
Now, we solve this square equation:
y=[-14⁺₋√(196+7200)] / 2=(-14⁺₋86)/2
We have two solutions:
y₁=(-14-86)/2=-50 ⇒x=14+y=14-50=-36
y₂=(-14+86)/2=36 ⇒x=14+y=14+36=50
Answer: we have two solutions:
Solution1: The first number is -36 and the other number is -50
Soltuion2: The first number is 50 and the other number is 36
Answer:
A
Step-by-step explanation:
Diameter = 32 in
r = 32/2 = 16 in
Surface area of sphere = 4πr²
= 4 * 3.142 * 16 * 16
= 3217.408
= 3217 in²
