Answer:

There are two zeros. The intercepts are -2 and -4

Step-by-step explanation:

The zeros of a parabola are the points where the parabola intersects with the x axis. In other words, they are when the y value equals zero.

In this case, we see that the parabola intersects the x axis at two different points. Those points are (0, -2) and (0, -4)

Hi my lil bunny!

Let's solve your equation step-by-step.

$\frac{1}{4} x^2+5=0$

For this equation: $a=0.25, b=0, c=5$

$0.25x^2 + 0x + 5 = 0$

Step 1: Use quadratic formula with $a=0.25, b=0, c=5.$

$x = \frac{-b ± \sqrt{b^2 - 4ac} }{2a}$

$x = \frac{-(0) ± \sqrt{(0)^2 -4 (0.25) (5) } }{2(0.25)}$

$x = \frac{0 ± \sqrt{-5} }{0.5}$

Answer : No Real Solutions.

Simplify expression 2g +3(g+5)

Sophie [7]

Answer:

$5g+15$

Step-by-step explanation:

To solve this question, we will first expand the expression using the distributive rule: $x(y+z)=xy+xz$

Therefore:

$2g+3(g+5)=2g+3*g+3*5$

Simplify:

$2g+3g+15$

Add up like terms:

$5g+15$

Find the value of each variable in the parallelogram.

kenny6666 [7]

Answer:

n = 12 , m = 5

Step-by-step explanation:

since it is said it is a parallelogram so opposite sides are equal

n = 12 (being opposite sides of parallelogram)

m + 1 = 6 (being opposite sides of parallelogram)

m = 6 - 1

m = 5

Hope it will help :)
