Answer:
g(x)=2x^2
Step-by-step explanation:
g(x)=kx^2
98=k(7)^2
or 98=49k
k=2
so g(x)=2x^2
From 4 p.m to 8 p.m, there are 4 hours. Each hour is composed of 60 minutes. This means that the total number of minutes is equal to 240. Thus, we determine the ratio of her time in doing the homework by dividing 10 minutes by 240 minutes, giving us the answer of 10:240 equal to 1:24.
Yes, there is a triangle with angle measures of 30°, 70°, and 80°.
No matter what the angle measures in a triangle are, they must add up to 180° for it to be a triangle. Even if it was 178°, 1°, and 1°, it would add up to 180° and make it a triangle.

Step-by-step explanation:
So, the equation is 2x + 6 = 2(x+5)
Let's solve your equation step-by-step.
2x+6=2(x+5)
Step 1: Simplify both sides of the equation.
2x+6=2(x+5)
2x+6=(2)(x)+(2)(5)(Distribute)
2x+6=2x+10
Step 2: Subtract 2x from both sides.
2x+6−2x=2x+10−2x
6=10
Step 3: Subtract 6 from both sides.
6−6=10−6
0=4
No, Alex is wrong. The correct expanded form would be 100+60+5+.03+.008
