No none of the sides have equal side lengths
ANSWER :
The values of x are -8 and 8
EXPLANATION :
From the problem, we have the equation :
![x^2-47=17](https://tex.z-dn.net/?f=x%5E2-47%3D17)
Add 47 to both sides :
![\begin{gathered} x^2-47+47=17+47 \\ x^2=64 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%5E2-47%2B47%3D17%2B47%20%5C%5C%20x%5E2%3D64%20%5Cend%7Bgathered%7D)
Take the square root of both sides :
Answer:
Step-by-step explanation:
Area of triangle is 40 cm² correct to nearest 5cm² .
∴ Area of triangle = ( 40 ± 5) cm²
∴ upper bound for area of triangle is = (40 + 5) cm² = 45cm²
Base of triangle = 9cm
∵ area of triangle = 1/2 base × height
height = 2 × area of triangle/base
∴ upper bound for height of triangle = 2 × upper bound area/base
= 2 × 45/9 = 10cm
Hence answer is 10cm
You just gotta do 3.14 • 8^2
Answer:
y = -
x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = -
and c = 5 , then
y = -
x + 5 ← equation of line
